Which CONCAMs can do photometry?
Posted: Mon Sep 27, 2004 1:52 am
I have now tried to do photometry with archived data from all of the CONCAMs from the last few months. If I was able to use the "different day, same sidereal time" technique and obtain a flat light curve with a known constant star, then that CONCAM statation was deemed capable of producing useful scientific photometry.
From West to East, the following CONCAMs produced scientifically believeable photometry files (using WOLF): HL, MK, KP, SA, and SD.
The following had problems:
MW (too few measurements, too few stars),
RH (too few recent measurements),
CP (photometry file returns yet unreliable),
CI (recent dust storms (?) making photometry strangely variable, unreliable),
WO (time of exposure start unreliable, files strangely repeated).
So for this month or so, NSL photometers should use only HL, MK, KP, SA, and/or SD data. In the meantime, we will try to bring as many of the others up to scientific usability as possible.
If anyone can do reliable photometry with CP or CI data please step forward!
