[vsnet-chat 5477] Re: (fwd) Assistance Needed with Light Curveof V1432 Aql

["Berto Monard" <LAGMonar@csir.co.za>]

I dont' know if Donn had a reply to that.

With my rather meagre knowledge on magnetic systems, I would suggest to
take the minimum as a reference for suspending the curves. 
The time of minimum most likely represents a well timed periodic event,
probably an eclipse of a bright part....possibly the system is slightly
inclined and we see only one column. It all looks quite interesting.
As soon as AB Nor and BF Ara stop with their nonsense, I'll have a go
at V1432 Aql too! ;-)

PS I would rather refer to an uncertainty of 0.03 magnitude (not an
error), although it probably only includes the standard deviation of the
noise (K-C), not?

Taichi:

I need some tutoring in light curve examination!  Please find the
composite
of three nights of clear photometry on V1432 Aql at my ftp side at:

http://starkey.ws/FTP%20Page/V1432%20Aql%20%20composite%20Photometry.jpg


  I have superimposed the curves and used the maxima as a
synchronization
point.  I was refocusing during the minima on the JD515 curve, so I may
have
missed the actual
minima.

Why don't the minimas and the later parts of the curves more closely
overlap?

Are there actually 2 maximas and minimas per cycle [phase], and I am
only
catching 1/2 of the total cycle?

Thanks!
