  @author Peter Weilbacher
  
        Sort input pixel tables into lists of files per exposure, merge pixel
        tables from all IFUs of each exposure.

        Correct each exposure for differential atmospheric refraction (unless
        --lambdaref is far outside the MUSE wavelength range, or NFM is used
        which has a built-in corrector).
        Then the flux calibration is carried out, if a response curve was given
        in the input; it includes a correction of telluric absorption, if a
        telluric absorption correction file was given.
        If observations were done with AO and a RAMAN_LINES file was given,
        a procedure is run to clean the Raman scattering emission lines from
        the data.
        Next, the slice autocalibration is computed and the flux correction
        factors are applied to the pixel table (if --autocalib="deepfield").
        If user-provided autocalibration is requested (--autocalib="user"),
        then the autocalibration is not computed on the input exposure but
        the autocalibration factors are read from the AUTOCAL_FACTORS table
        and applied directly to the data.
        Then the sky subtraction is carried out (unless --skymethod="none"),
        either directly subtracting an input sky continuum and an input sky
        emission lines (for --skymethod="subtract-model"), or
        (--skymethod="model") create a sky spectrum from the darkest fraction
        (--skymodel_fraction, after ignoring the lowest --skymodel_ignore as
        artifacts) of the field of view, then fitting and subtracting
        sky emission lines using an initial estimate of the input sky lines;
        then the continuum (residuals after subtracting the sky lines from the
        sky spectrum) is subtracted as well. If --save contains "skymodel", all
        sky-related products are saved for each exposure.
        Afterwards the data is corrected for the radial velocity of the
        observer (--rvcorr), before the input (or a default) astrometric
        solution is applied.
        Now each individual exposure is fully reduced; the pixel tables at this
        stage can be saved by setting "individual" in --save.

        If multiple exposures were given, they are then combined. If --save
        contains "combined", this final merged pixel table is saved.

        Finally (if --save contains "cube"), the data is resampled into a
        datacube, using all parameters given to the recipe. The extent and
        orientation of the cube is normally computed from the data itself, but
        this can be overridden by passing a file with the output world
        coordinate system (OUTPUT_WCS), for example a MUSE cube. This can also
        be used to sample the wavelength axis logarithmically (in that file set
        "CTYPE3='AWAV-LOG'").
        As a last step, the computed cube is integrated over all filter
        functions given (--filter) that are also present in the input filter
        list table.
