Problems about computing a psf star!!
FabÃola Campos wrote on Aug 31, 2006
I was trying to compute a psf for a star in a crowed field, using the guide that help in psf task provides. However, the computed psf was full of holes and definitively it did'nt look like a psf star. So I thought that I could be doing something wrong and I decided to make the examples that help psf has, it is for an image called dev$ypix. I follwed all the instructions that the exercise has, but in the end the computed psf had the same bad characteristics!! And I don't know the reason!!!
Then I thought that someone here could help me to solve this problem, or give me a tip. Can anybody help me???

You might want to look through the "Users Guide to Stellar Photometry with IRAF" guide; there are some pretty explicit step-by-step instructions on how to construct a PSF in a crowded field.
