Re: GSC 748-1618

GSC 748-1474  V=10.96  B-V=0.97
GSC 748-1662  V=11.00  B-V=0.43

According to the same source (Tycho-2) the variable (?) star is V=11.07 
and B-V=0.97.

In getting these values for you I noticed that I had a mistake in the V 
mags I used on my comp stars earlier when I said that I observed the 
star at 10.8. That is wrong. I mistyped the formula on my hand 
calculator. I need to redo that photometry with the correct V values. 
That's why I write perls scripts to do my calculating for me!
