For a given RA and DEC, the cone search returns all objects within the search radius that meet
your search constraints.
Proximity Search allows you to enter a list of RA/Dec positions and find objects
near those positions. For each RA and Dec you enter, the proximity search
returns objects within the specified search radius that meet your search
constraints.
The list can be either entered directly into the box or uploaded as a file.
In either case, the positions must be of the form:
with each item separated by a comma or space. The first two numbers, "ra" and "dec,"
are requried - these are the sky positions (J2000) around which to search.
The third, "sep," is optional - it is the separation distance or seach radius,
in arcminutes, around which to search. If you do not enter a value for "sep,"
the default is 1 arcminute.
"Nearest Only" returns only one match for each position you enter - the sky object meeting your search criteria that is nearest to the position you entered.
"All Nearby" returns all objects meeting your criteria within your search radius.
That means that "Nearest Only" only will return at most one match for each position you entered; "All Nearby" could return many matches for each position.
Which spectroscopic constraints (if any) do you want applied to your query?
Redshifts less than zero are possible (e.g., for stars), as are
redshifts greater than 5 (some QSOs, but also objects with poorly
measured redshifts). The "Redshift warning flags" toggle allows
you to remove the constraint that there should be no redshift warnings
(default). Uncheck this if you want to allow spectra that have
redshifts with warnings associated with them. The warning flags
are encoded as bits in the zWarning column in
the SpecObjAll table.
What type of objects (as automatically classified by their spectra) do
you want returned from your query?
Which type of objects do you want returned from your query? (Here, the
object type is from the spectroscopic target selection algorithms, where
the objects have been classified photometrically or by matchup with
other catalogs.) (primary target categories)
The primTarget field is a bit mask specifying which primary target categories the object was selected in. If you select
one or more bits in the At least one of these bits ON menu, then the bit-wise OR of each of those bits is
computed and it must be greater than 0. If you select one or more of the bits in the
All of these bits OFF menu,
then the bit-wise AND of all those bits is computed and it must be equal to 0.
Which type of objects do you want returned from your query? (Here, the
object type is from the spectroscopic target selection algorithms, where
the objects have been classified photometrically or by matchup with
other catalogs.) (secondary target categories)
The secTarget field is a bit mask specifying which primary target categories the object was selected in. If you select
one or more bits in the At least one of these bits ON menu, then the bit-wise OR of each of those bits is
computed and it must be greater than 0. If you select one or more of the bits in the
All of these bits OFF menu,
then the bit-wise AND of all those bits is computed and it must be equal to 0.
Which imaging constraints (if any) do you want applied to your query?
Do you want to search over given range in u, g, r, i, and/or z
magnitudes?
Do you want to search over given range in u-g, g-r, r-i, and/or i-z
colors?
Which type of objects do you want returned from your query? (Here, the
object type is the classification from the photometric pipeline, and are
based upon how well an object matches a stellar, de Vaucouleurs, or
exponential profile.)
You can restrict the search to objects that have minimum photometric quality
as determined by the score column in the
PhotoObjAll table.
The possible values of score are 0 and 1 (0=BAD, 1=ACCEPTABLE). Independently of this
constraint, you may also opt to return the score value from the PhotoObjAll table for each object in your search, by checking the
"Return value" checkbox. If no value is entered in the "Match Score" box, no quality constraint will be applied but the
score
will still be returned with your query results.
Photo flags can be set (ON) or (OFF). If you select one or more flags in the At least one of these flags ON menu, then
the bit-wise OR of each of those flag bits is computed and it must be greater than 0. If you select one
or more of the flags in the All of these flags OFF menu, then the bit-wise AND of all those flag bits is computed and
it must be equal to 0.
name | value | description |
CANONICAL_CENTER | 0x0000000000000001 | Measurements used the center in r*, rather than the locally determined center. |

PEAKCENTER | 0x0000000000000020 | Given center is position of peak pixel, rather than based on the maximum-likelihood estimator. |
NODEBLEND | 0x0000000000000040 | No deblending was attempted on this object, even though it is BLENDED. |
NOPROFILE | 0x0000000000000080 | Object was too small or too close to the edge to estimate a radial profile. |
NOPETRO | 0x0000000000000100 | No valid Petrosian radius was found for this object. |
MANYPETRO | 0x0000000000000200 | More than one Petrosian radius was found. |
NOPETRO_BIG | 0x0000000000000400 | Petrosian radius is beyond the last point in the radial profile. |
DEBLEND_TOO_MANY_PEAKS | 0x0000000000000800 | There were more than 25 peaks in this object to deblend; deblended brightest 25. |
COSMIC_RAY | 0x0000000000001000 | Contains a pixel interpreted to be part of a cosmic ray. |
MANYR50 | 0x0000000000002000 | Object has more than one 50% light radius. |
MANYR90 | 0x0000000000004000 | Object has more than one 90% light radius. |
BAD_RADIAL | 0x0000000000008000 | Some of the points in the given radial profile have negative signal-to-noise ratio. Not a significant parameter. |
INCOMPLETE_PROFILE | 0x0000000000010000 | Petrosian radius intersects the edge of the frame. |
INTERP | 0x0000000000020000 | Object contains one or more pixels whose values were determined by interpolation. |
SATURATED | 0x0000000000040000 | Object contains one or more saturated pixels |
NOTCHECKED | 0x0000000000080000 | There are pixels in the object which were not checked to see if they included a local peak, such as cores of saturated stars. |
SUBTRACTED | 0x0000000000100000 | This BRIGHT object had its wings subtracted from the frame |
NOSTOKES | 0x0000000000200000 | Object has no measured Stokes params |
BADSKY | 0x0000000000400000 | The sky level is so bad that the highest pixel in the object is very negative; far more so than a mere non-detection. No further analysis is attempted. |
PETROFAINT | 0x0000000000800000 | At least one possible Petrosian radius was rejected as the surface brightness at r_P was too low. If NOPETRO is not set, a different, acceptable Petrosian radius was found. |
TOO_LARGE | 0x0000000001000000 | The object is too large for us to measure its profile (it extends beyond a radius of approximately 260), or at least one child is larger than half a frame. |
DEBLENDED_AS_PSF | 0x0000000002000000 | Deblender treated obj as PSF |
DEBLEND_PRUNED | 0x0000000004000000 | At least one child was removed because its image was too similar to a supposedly different child. |
ELLIPFAINT | 0x0000000008000000 | Object center is fainter than the isophote whose shape is desired, so the isophote properties are not measured. Also flagged if profile is incomplete. |
BINNED1 | 0x0000000010000000 | Object was detected in 1x1 binned image |

NODEBLEND_MOVING | 0x0000000200000000 | A MOVED object that the deblender did not treat as moving. |
TOO_FEW_DETECTIONS | 0x0000000400000000 | A child of this object was not detected in enough bands to reliably deblend as moving. |
BAD_MOVING_FIT | 0x0000000800000000 | Moving fit too poor to be believable. |
STATIONARY | 0x0000001000000000 | This object was consistent with being stationary. |
PEAKS_TOO_CLOSE | 0x0000002000000000 | At least some peaks within this object were too close to be deblended, thus they were merged into a single peak. |
MEDIAN_CENTER | 0x0000004000000000 | Center given is of median-smoothed image. |
LOCAL_EDGE | 0x0000008000000000 | Center in at least one band is too close to an edge. |
BAD_COUNTS_ERROR | 0x0000010000000000 | An object containing interpolated pixels had too few good pixels to form a reliable estimate of its error; the quoted error may be underestimated. |
BAD_MOVING_FIT_CHILD | 0x0000020000000000 | A possible moving child's velocity fit was too poor, so it was discarded and the parent was not deblended as moving. |
DEBLEND_UNASSIGNED_FLUX | 0x0000040000000000 | After deblending, a significant fraction of flux was not assigned to any children. |
SATUR_CENTER | 0x0000080000000000 | Object center is close to at least one saturated pixel. |
INTERP_CENTER | 0x0000100000000000 | Object center is close to at least one interpolated pixel. |
DEBLENDED_AT_EDGE | 0x0000200000000000 | An object close enough to the edge of the frame normally not deblended, is deblended anyway. Only set for objects large enough to be EDGE in all fields/strips. |
DEBLEND_NOPEAK | 0x0000400000000000 | There was no detected peak within this child in at least one band. |
PSF_FLUX_INTERP | 0x0000800000000000 | Greater than 20% of the PSF flux is from interpolated pixels. |
TOO_FEW_GOOD_DETECTIONS | 0x0001000000000000 | A child of this object had too few good detections to be deblended as moving. |
CENTER_OFF_AIMAGE | 0x0002000000000000 | At least one peak's center lay off of the atlas image. This can happen when the object is deblended as moving, or if the astrometry is bad. |
DEBLEND_DEGENERATE | 0x0004000000000000 | Two or more candidate children were essentially identical; one one was retained. |
BRIGHTEST_GALAXY_CHILD | 0x0008000000000000 | This child is the brightest family member (in this band) that is classified as a galaxy. |
CANONICAL_BAND | 0x0010000000000000 | This is the 'canonical' band; r unless the object is undetected in the r filter. |
AMOMENT_FAINT | 0x0020000000000000 | Object was too faint to measure weighted moments such as mE1_g; unweighted values are reported. |
AMOMENT_SHIFT | 0x0040000000000000 | Centroid shift too large when measuring adaptive moments. Row/Column shifts are reported in mE1, mE2. |
AMOMENT_MAXITER | 0x0080000000000000 | Maximum number of iterations exceeded measuring e.g. mE2_g; unweighted values are reported. |
MAYBE_CR | 0x0100000000000000 | There is reasonable suspicion that this object is actually a cosmic ray. |
MAYBE_EGHOST | 0x0200000000000000 | There is reasonable suspicion that this object is actually a ghost produced by the CCD electronics. |
NOTCHECKED_CENTER | 0x0400000000000000 | The center of this object lies in a region that was not searched for objects. |
OBJECT2_HAS_SATUR_DN | 0x0800000000000000 | The electrons in this saturated object's bleed trails have been included in its estimated flux. |
OBJECT2_DEBLEND_PEEPHOLE | 0x1000000000000000 | Deblend was modified by the deblender's peephole optimiser. |
GROWN_MERGED | 0x2000000000000000 | Growing led to a merger |
HAS_CENTER | 0x4000000000000000 | Object has a canonical center |
RESERVED | 0x8000000000000000 | Not used |
