This page is to generate image cutouts of SDSS images based upon a
user defined list of object positions. In order to avoid congestion
on the server, the list is currently limited to 1000 objects.
If this is a problem, please submit your list in pieces.|
If you're new to the Image List tool, see its entry in
For the description of the other options see the Help
section of the Finding Chart.
The format of the list can be from the following choices:
- List of (ra,dec) pairs
Always ra comes first, followed by dec.
Both ra and dec can be in degrees or hh:mm:ss.s dd:mm:ss.s format. The separator
can be any white space or a comma.
- List of (name,ra,dec) triplets
The fields must always be in this order. The name can be
any single alphanumeric string containing at most an underscore and a
dot (like ABC_1234.32). Both ra and dec can be in degrees or hh:mm:ss.s dd:mm:ss.s format.
The separator can be any white space or a comma.
- Same as above, with a single header line
The formats (1) and (2) can also contain a single header line,
containing the column names. The header must use the same separator as the data.
The names ra and dec are mandatory.
