Spectroscopy

In a similar way as is already implemented in FIES, we are developing scripts that automatically take properly illuminated calibration spectra for a given set-up. In principle, the scripts takes a short exposure of a small area on the CCD to check the count-rate which by comparison to a desired value defines the required exposure time. The measure count-rate (or resulting exposure time) can also be used to check the health of the lamp(s) used.

We plan to add specific examples on the observing and reduction strategy to best correct for fringes when observing with the red grism #5.
