Hello everybody!

What task in IRAF exept DISPCOR can help me to do rebinning (or to change pixel scale, "pixel scale" is number of angstroms contained in one pixel ) spectra ?

Thanks for your attention!

Hello,

For spectra the rebinning tasks in IRAF are DISPCOR and TRANSFORM. For images the main task is GEOTRAN. The differ in allowed dimensionality of the input data and how the transformation is specified. The choice of resampling function is generally up to the user.
