>> For comparison:
>>    07 04 04.786 -03 50 50.24  GSC
>>    07 04 04.846 -03 50 51.11  USNO A2.0
>>    07 04 04.82  -03 50 50.5   2MASS

...and a few more:

       7 04 04.82  -03 50 50.6   GSC v1.2
       7 04 04.83  -03 50 50.5   GSC-ACT
       7 04 04.782 -03 50 50.48  GSC-2.2
       7 04 04.874 -03 50 50.78  SuperCOSMOS

(GSC v1.1 should not be used any longer since the sometimes-large systematic
errors have been eliminated in both v1.2 and GSC-ACT.)
