LBT/LUCI: Non-linearity correction

[kbwestfall]

Is the non-linearity correction in the correct place for LBT/LUCI? This may be a more general issue with all spectrographs. See here.

The non-linearity correction should be applied to the crosstalk-corrected data. Further operations (e.g. dark subtraction) would come later. So I believe that what the code example given (i.e. in lbt_luci.py, the correction is made in the get_rawimage function) is the correct place.

The crosstalk-correction has not yet been published on the webpages.
When it is available, it could also be implemented in get_rawimage.
