CAT contains several catalogs each stored in a separate table in the database. The database currently contains the following catalogs:
Each catalog display table contains the following minimum set of information:
Column Name | Description |
---|
ID | integer indicating the ID (primary key) in the database table |
Name | if catalog does not contain name, it will be a unique construct depending on the catalog |
Right Ascension | |
Declination | |
Epoch | |
Proper Motion in RA*cos(dec) | mas/yr |
Proper Motion in Declincation | mas/yr |
Magnitude | |
Distance | arc minutes (from the center for the original query) - Computed at the time of query |
A text file containing the observer's target list can be loaded and displayed in a separate tab along with the catalog searches. The file should contain name (enclosed in double quotes), RA, DEC, epoch, proper motion in RA (mas/yr), proper motion in DEC (mas/yr), and magnitude. Please refer to Target View for more details.
FK6
The FK6 catalog provides the following additional parameters:
Column Name | Description |
---|
FK6 Number | the internal ID from the catalog |
