CAT contains several catalogs each stored in a separate table in the database. The database currently contains the following catalogs:

  • FK6
  • TYCHO
  • GWAVES (a composite catalog of UCAC2 & UCAC3 limited to declinations observable at DCT)
  • UCAC2
  • UCAC3UCAC4

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

arcsec arc minutes (from the center for the original query) - Computed at the time of query

Last Modified

Timestamp from the last modification date in the database

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.
Example Format:

...

"HR 173" 00 40 32.9 -23 48 16  2000.0  4.4 -34.2 11.5
"Gl 15 A" 00 18 22.9999  44 01 23  2000  2888.92 410.10 13.5
"DELTA SGE " 19 47 23.2  18 32 03  1950  -4.31 12.35 5.3
