Hi Guys,


Sorry to bother you but I seem to be struggling with the data analysis. I am trying to run a comparison study between IRAF and AIP4WIN for extracting Magnitudes. I seem to be struglling to use AIP4WIN and my other question is what is the easiest method of performing differential photometry for already extracted magnitudes from IRAF.

Using AIP4Win

Hi,

I've been using AIP4Win for a few years and may be able to help with that. I have no experience with IRAF so I won't make any comments there. But before I can start please provide a bit more detail. 

monochrome CCD or DSLR images?

Are they already calibrated (bias, dark and flat corrected) or do you want AIP4Win to do that step too?

Are you processing a timeseries of multiple images of the same field?

Anything else that may be relevant?

Cheers,

Mark
