hi,
i'm an IRAF beginner and currently going through the exercises tutorial. my problem is : why do we fit a chebyshev function of order 1in the "colbias" section? why not a legendre or spline? is it because we are using an averge?
please help............Amal Mirando [color=red:87b04a4c30][Mod Note: Forwarded from 'Submissions' link][/color:87b04a4c30]

Yes, the intent is to subtract the average of the bias region.
