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.
