Re: GSC 540-84

Got one more long night on this one. I've made a web page for it here:

http://www.lolife.com/astronomy/gsc540-84/


I tried phasing the data with Patrick's period:

It looks a bit odd. My comp star 1-sigma was less than 0.01 so even if 
you double it, that 0.05 mag difference at phase 0 is outside the error 
bars. We don't know if the period is right and I'm sure there are 
factors (e.g. color/airmass) that could account for the difference. 
When you double the period it still seems possible but that light curve 
shape doesn't really scream EB at me.

This is Rc data. Can someone grab some V data for us? Otherwise after a 
few more nights in Rc I'll switch to V.

I'll add some of this to the wiki page for this star.

Cheers,
