On the RELCO starter spectrum below, my CCDSPEC spectrum is graphed against the ALPY spectrum from Three HIlls Observatory from Robin above, and I have marked the lines I identified together with those lines that ISIS use for calibration – this gives some more lines for me to use at LRO.
Comment from Robin at Three Hills Observatory (https://stargazerslounge.com/topic/226911-neon-lamp-to-set-spectroscope/), “Your spectrograph has roughly the same resolution as the ALPY (R~500) and these lines are known to be reliable and give a very accurate calibration to better than 1A with the ALPY. I have attached a list of wavelengths of the 13 lines. They correspond to lines identified in the spectrum by Richard Walker using his DADOS with 200l/mm grating (R 900). If you identify as many of the lines in your spectrum as possible and make a 3rd order fit, any wrongly identified lines will immediately stand out as they will have larger errors.”
