Re: GSC 00279 00321 paper

Well, I decided to go back and redo my photometry using V-C and the same 
guide star that Dirk used. The guide star in question is GSC 00279-00356. 
By using the Tycho2 formula I come up with a magnitude of V=10.78 for it. 
I looked it up on CD23 (seq 92576) and averaged it out and I get V=10.98. 
GSC has it at 10.76. You think I should use the TASS value of 10.98? Or 
should I just leave it as differential and forget it? The TASS data is not 
differential, is the only thing.
