[Aavso-photometry] TrES-1

[Arne Henden]

I've put a rough UBVRI calibration of the field for this
planet transit system on
ftp://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/tres1.dat
I don't trust the absolute calibration very well, but in
relative terms, it is pretty good.  There are a number of
equally bright comparison stars within my 11x11arcmin FOV,
so it should be an easy system to follow (much easier than
HD209458!).
   I'll do a real calibration when the weather permits.
