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 
restrained about.

Thanks for the calibration homework.
