Thanks Robin, that;s very interesting and not something I had thought about before. I can see in BASS the filtering option under the ‘Resample Profile’ tab which offers a couple of options, ‘low pass’ and ‘low pass Gaussian’. The Gaussian option looks to deliver the better filtered profile in comparison to my Star Analyser spectra.
Much appreciated
Hugh
