pypeit_sensfunc does not currently work on OneSpec files, but this is necessary for e.g. MOSFIRE long2pos.

Hi All,

Leonor Arriscado pointed out this issue with PypeIt which I think she also brought up to @debora-pe in the User Slack. Basically, if one is using MOSFIRE long2pos to observe standards at different mask locations, then one wants to coadd1d these standards to obtain a combined flux standard (in counts) and then run pypeit_sensfunc on the OneSpec file. However, pypeit_sensfunc does not accept OneSpec files but only spec1d files. It should be possible to run pypeit_sensfunc on OneSpec files (although obviously not for echelle sensitivity functions). There are some things to think about here since the sensfunc class uses the blaze optionally, and there is no blaze packaged with OneSpec files, but I don't think this is a significant drawback since one can simply compute sensitivity functions without the blaze. I think that the sensfunc class should be modified to accommodate OneSpec files.
