[Aavso-photometry] IL Aqr: Campaign Update 041014 (1 week to go!)

[Arne Henden]

"Ballpark" is relative: your position is about an arcsec different
than mine.  You would be thrown out as an astrometrist. :-)
I would *not* blame wcstools, just your use of that package.
There is another astrometry toolkit for iraf that was mentioned
in the mpml a few years ago called autoast:
http://wise-obs.tau.ac.il/~eran/iraf/astrometry.html
which might be of interest to people.
   IL Aqr is very red; my Ic-band exposures to obtain BVRI colors
of the variable were only one second in duration and nearly
saturate.  I don't like red stars much; the spectra are wierd,
making accurate wide-band photometry difficult, and because they
increase in brightness so dramatically from the blue to the red, it is
difficult to find a single comparison star that gives proper signal/noise
at all wavelengths.
