Geoff,
The spectral processing package to try is John's BASS Project.
It does everything you need and is quite capable of producing ProAm quality results.
Highly recommended. https://uk.groups.yahoo.com/neo/grou...dger/links/all
Hi Goff, I use BASS and ISIS on windows 10 OK, as Ken says BASS is very good, on the BASS site there is a very good tutorial (Processing Alpy Spectra using BASS ) DONT BOTHER ABOUT THE ALPY MOST OVE IT WERCKS FOR ANY SPECTRUM.
