[Aavso-photometry] IL Aqr Sequence

[Michael Koppelman]

This is basically for my own amusement, just like everything I do, but 
if anyone was trying to do ensemble photometry perhaps it could be of 
use. Astrometry is against Tycho-2 (sorry, it was all I had with me). 
Don't know why the Rc error is so high. This was at airmass=2.0 or so 
which breaks my calibration a bit, which is optimized for airmass=1.25. 
This is based off of a single night. It does match the E chart fairly 
well. You can see that the variable star is much redder than anything 
around it. That was my main goal in doing this.

Use at your own risk. I welcome your feedback.

Cheers,
Michael Koppelman
