Hi Berto et al.,
Yeah, CD Ind is a long-term project, following the synchronization of
that wayward white dwarf. Your early-season data specifies the phase
pretty well; a rush of late-season data, and a couple of mid-season
points sprinkled in there, will do the job nicely. But VY Aqr in a July
superoutburst, now that's just too delicious to resist... or even to be
Thanks for the calibration homework.

> VY Aqr 16 21 12 11.2 -08 49 59 h 5772-0074 13.82 0.75 0.42
> VY Aqr 1v 21 12 11.3 -08 53 08 G 5772-0143 10.97 0.55
>>From the latter we can derive an R magnitude of 10.65 for unfiltered reference. For the others subtract the third column values (V-R) from the first column (which is V).
