Simple mkobsfile + invertfit question
Gabriel wrote on Sep 13, 2010
Hi,
this is my question: which one (if any) of this tasks (mkobsfilke, invertfit) is the one in charge of matching stars across different exposures?
I'm working with a field observed in 4 different fields through 3 different exposure times. I realized that after running my '.als.1' files (allstar task output) through mkobsfile and then inverfit, the final file shows clearly stars that are found in several exposure times but counted as a different star each time. Shouldn't one of this tasks try to match stars through different exposure times so as to keep the star found in the longest exposure possible?
I'm under a deadline so this is kinda urgent to me, any response will be greatly appreciated.
Cheers!

See the MKIMSETS task as well as "help pcintro" for an overview of PHOTCAL.

I read those topics, but I couldn't find anywhere which task is in chatge of the matching. I'm guessing 'mkobsfile' is, but in that case it's not working for me for some reason...
The imset and params files I write by hand, so I don't use the 'mkimsets' task.
Tanks anyway, I'll see what I can do.
