Making slow progress with my processing pipeline. I think I can work on the response curve a little, all my spectra include an oscillation in the continuum which seems to be fairly uniform.
I now have a command line driven workflow to dark subtract, crop, bin, detect zero order and calibrate to predetermined A/px, wavelength crop, normalise and stack which works OK for me. I then do the response correction in splat-vo.
I must say I was sceptical of how effective the response correction was going to be against anything other than my reference star, but have been pleasantly surprised to see at least a vague match between my spectra and the corresponding pickles references.
Attached are Fomalhaut (A3V), Alpha Cen A (G2V - contaminated with Alpha Cen B) and Antares (M1.5Iab). My spectra are in red, pickles references in grey.
Still can't seem to do anything about the cloud though ...
