Hi John,

Your  wavelength error trend using just the lamp lines seems similar to mine qualitatively eg post #37.  Your variable offset as shown at H alpha is different to what I see though. My calibration is consistently good at H alpha.

I now have some data for the Filly lamp (I used the “cross” lamp which is just Argon)  There does appear to be  something subtly different. I will report back when I have figured out what is going on.

Cheers

Robin
