[Aavso-photometry] HMXB charts

[Gordon Sarty]

The HMXB charts on

http://www.usask.ca/psychology/sarty/AAVSO_HMXB_Charts.html

are all updated and are stable barring problems like the discovery of a 
variable comp star. Please use the updated charts and submit your 
observations directly to WebObs. We should be able to track the data in 
the light curve generator as usual.

Clear Skies!

> All four fields *have* been observed at SRO, and BVRcIc photometry
> is available.  I expect Gordon and Richard to extract the magnitudes
> for their comp stars sometime soon.  I agree that "d" is too red
> for a good comparison star.

> This will be a tough campaign, as there are 4 targets to follow
> (instead of just SS Cyg); the necessary precision will tax your
> ability to perform photometry (a good thing!); combining datasets
> that have not been transformed will require significant overlap;
> long time series will show trends due to extinction; etc.
