I had several attempts at getting an instrument response with this one. To compare in the way you say, I had to load the corrected profile and the MILES spectrum into BASS – I couldn’t see an easy way of overlaying the two?
Also, my reference stars are probably not ideal so far…. I see in one of your posts here you recommend type A as reference. My criteria were that it was at roughly the same altitude, similar magnitude, and visible with my horizon (not trivial :). Next time, I’ll search a bit harder to get something closer to an A-type (the current one is F8). I guess the A-type have nice peaked shapes that lend themselves to this process.
