Detailed Description

Author:
Peter Weilbacher

Merge pixel tables from all IFUs and correct for differential atmospheric refraction.

To derive the flux response curve, integrate the flux of all objects detected within the field of view using the given profile. Select one object as the standard star (either the brightest or the one nearest one, depending on --select) and compare its measured fluxes to tabulated fluxes to derive the sensitivity over wavelength. Postprocess this sensitivity curve to mark wavelength ranges affected by telluric absorption. Interpolate over the telluric regions and derive a telluric correction spectrum for them. The final response cuve is then linearly extrapolated to the largest possible MUSE wavelength range and smoothed (with the method given by --smooth). The derivation of the telluric correction spectrum assumes that the star has a smooth spectrum within the telluric regions.

If there are more than one exposure given in the input data, the derivation of the flux response and telluric corrections are done separately for each exposure. For each exposure, the datacube used for flux integration is saved, together with collapsed images for each given filter.
