DAP MAPS File Construction

Analysis class: :class:`~mangadap.dapfits.construct_maps_file`

File Root: $MANGA_SPECTRO_ANALYSIS/$MANGADRP_VER/$MANGADAP_VER/[PLATE]/[IFUDESIGN]

File Template: manga-[PLATE]-[IFUDESIGN]-MAPS-[DAPTYPE].fits.gz

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_ELLCOO, SPX_MFLUX, SPX_MFLUX_IVAR, and SPX_SNR maps from the :class:`~mangadap.proc.reductionassessments.ReductionAssessment` object using :func:`~mangadap.dapfits.construct_maps_file.reduction_assessment_maps`.
• Combine the BINID extensions from the :class:`~mangadap.proc.spatiallybinnedspectra.SpatiallyBinnedSpectra`, :class:`~mangadap.proc.stellarcontinuummodel.StellarContinuumModel`, :class:`~mangadap.proc.emissionlinemoments.EmissionLineMoments`, :class:`~mangadap.proc.emissionlinemodel.EmissionLineModel`, and :class:`~mangadap.proc.spectralindices.SpectralIndices` objects using :func:`~mangadap.dapfits.combine_binid_extensions`.
• Construct the BIN_LWSKYCOO, BIN_LWELLCOO, BIN_AREA, BIN_FAREA, BIN_MFLUX, BIN_MFLUX_IVAR, BIN_MFLUX_MASK, and BIN_SNR extensions from the :class:`~mangadap.proc.spatiallybinnedspectra.SpatiallyBinnedSpectra` object using :func:`~mangadap.dapfits.construct_maps_file.binned_spectra_maps`.
• Construct the STELLAR_VEL, STELLAR_VEL_IVAR, STELLAR_VEL_MASK, STELLAR_SIGMA, STELLAR_SIGMA_IVAR, STELLAR_SIGMA_MASK, STELLAR_SIGMACORR, and STELLAR_FOM extensions using the :class:`~mangadap.proc.stellarcontinuummodel.StellarContinuumModel` object using :func:`~mangadap.dapfits.construct_maps_file.stellar_continuum_maps`.
• Construct the EMLINE_SFLUX, EMLINE_SFLUX_IVAR, EMLINE_SFLUX_MASK, EMLINE_SEW, EMLINE_SEW_CNT, EMLINE_SEW_IVAR, and EMLINE_SEW_MASK extensions using the :class:`~mangadap.proc.emissionlinemoments.EmissionLineMoments` object using :func:`~mangadap.dapfits.construct_maps_file.emission_line_moment_maps`.
• Construct the EMLINE_GFLUX, EMLINE_GFLUX_IVAR, EMLINE_GFLUX_MASK, EMLINE_GEW, EMLINE_GEW_CNT, EMLINE_GEW_IVAR, ``EMLINE_GEW_MASK, EMLINE_GVEL, EMLINE_GVEL_IVAR, EMLINE_GVEL_MASK, EMLINE_GSIGMA, EMLINE_GSIGMA_IVAR, EMLINE_GSIGMA_MASK, EMLINE_INSTSIGMA, EMLINE_TPLSIGMA, EMLINE_GA, EMLINE_GANR, EMLINE_FOM, and EMLINE_LFOM using the :class:`~mangadap.proc.emissionlinemodel.EmissionLineModel` object using :func:`~mangadap.dapfits.construct_maps_file.emission_line_model_maps`.
• Construct the SPECINDEX, SPECINDEX_IVAR, SPECINDEX_MASK, SPECINDEX_CORR, SPECINDEX_MODEL SPECINDEX_BF, SPECINDEX_BF_IVAR, SPECINDEX_BF_MASK, SPECINDEX_BF_CORR, SPECINDEX_BF_MODEL SPECINDEX_WGT, SPECINDEX_WGT_IVAR, SPECINDEX_WGT_MASK, SPECINDEX_WGT_CORR, SPECINDEX_WGT_MODEL extensions using the :class:`~mangadap.proc.spectralindices.SpectralIndices` object using :func:`~mangadap.dapfits.construct_maps_file.spectral_index_maps`.
• Compute the griz S/N metrics to include in the header and which then get propagated to the DAPall file using :func:`~mangadap.dapfits.add_snr_metrics_to_header`.
• Finalize the DAP primary header, which primarily constructs the :ref:`metadatamodel-dapqual` bit using :func:`~mangadap.dapfits.finalize_dap_primary_header`.
• Flag any map data that is not already flagged and does not have a positive inverse variance with both the MATHERROR and DONOTUSE bits.
