reconstructing iraf spectra? [message #66017] Tue, 07 April 2009 09:00

Hi all,

I wonder if anyone in the astro-IDL community has code that reconstructs
wavelength information from an iraf-style FITS header? I have some echelle
spectra with many orders per file. The FITS header has a series of
polynomial coefficients the iraf uses to construct its wavelength
information. I thought I'd check to see if anyone has written code that
converts this header to wavelength arrays, before I write it myself?

cheers
chris
