Hello, I've written some IDL routines to find lines in spectral data, and am about to
draft another procedure to determine spectral line parameters (strength,...), etc.
Does a routine for measuring line strengths in spectral data alreading exist?
Thanx, George

Various parameters of interest.
FYI: I located the IUE-RDAF IDL library procedures: feature.pro,... which is an
interactive tool for measuring line parameters. Are there others?
