[Aavso-photometry] RE AN #348 Request to Observe HMXBs

RE AN #348 – Request to Observe HMXB’s 

This presented as an April/May effort

In reading the referenced article:  “Finding Periods
in High Mass X-Ray Binaries,” specifically pages 6 & 7
(Observing Methods):

http://arxiv.org/abs/astro-ph/0702248

The request appears to be for “Continuous Coverage”
similar to that of the SS Cyg campaign, if I am
reading it correctly.

In addition the request is for BVRI observations.

If the above two criteria are in fact what is being
requested of for the four targets presented I think it
would be wise to have observers post to this list the
following:

Subject Box: HMXB Obs

AAVSO Desig. #
UT Start Obs Time
Estimated Ending UT Time
Filter(s) Using

So that other observers can best determine how to
“maximize” their own contributions.

In as much as only one of the four targets has comps
currently available it is suggested that we submit the
differentials (mobj –mcheck) directly to Dr. Sarty.

I think that in the case of TS this could be “awkward”
until comps are generated and would suggest only some
mid point or single obs be reported directly, at this
time
.. But it’s not my decision; this one is up to
the Dr. I will go with the flow and do what is
requested.  

My initial 2 cents
