Important class dependencies:
All of the main DAP classes:
- :class:`~mangadap.proc.reductionassessments.ReductionAssessment`
- :class:`~mangadap.proc.spatiallybinnedspectra.SpatiallyBinnedSpectra`
- :class:`~mangadap.proc.stellarcontinuummodel.StellarContinuumModel`
- :class:`~mangadap.proc.emissionlinemoments.EmissionLineMoments`
- :class:`~mangadap.proc.emissionlinemodel.EmissionLineModel`
- :class:`~mangadap.proc.spectralindices.SpectralIndices`
:class:`~mangadap.util.fitsutil.DAPFitsUtil`: Contains many convenience methods that, e.g., reconstruct a set of maps or datacubes based on input data sorted by bin ID and a map with the location of each bin ID.
Algorithm:
- Check the input types
- Initialize the primary header by copying over the DRP header and adding the DAP version information.
- Construct the
SPX_SKYCOO

,SPX_MFLUX
,SPX_MFLUX_IVAR
, andSPX_SNR
maps from the :class:`~mangadap.proc.reductionassessments.ReductionAssessment` object using :func:`~mangadap.dapfits.construct_maps_file.reduction_assessment_maps`.- Combine the
