Chopping the ends of spectra
nrowell wrote on Apr 26, 2007
Hi,
Just wondered if anyone can help me with this. I'm working with some spectra that are very noisy at one end, and i want to chop the last 1000A off. I've tried various tasks in IRAF and can't find anything to do this. Does anyone know of a suitable method?
Cheers,
Nick

See the SCOPY task a a way to copy out everything but the noisy bits. If the wavelength range is variable, something like SLIST can be used in a script to determine the dispersion and wavelength range for each spectrum.
