Detailed description of the data product
========================================
.. DetailedDescStart

This output product collects environmental/instrumental information
for a filter of an instrument to ultimately compute depth maps.

This output product is composed of **InfoMapMOC**, a container with a FITS file
in MOC HEALPix format (of type le3.id.vmpz.mocinfomap) collecting environmental/instrumental
information for a filter of an instrument to ultimately compute depth maps.
A raw description with polygons of the envelope of the sky covered is added as well
to ease future queries on the product (**SpatialCoverage** metadata, see `spatialFootprint <https://gitlab.euclid-sgs.uk/ST-DM/ST_DataModel/blob/develop/dictionary/bas/cot/euc-test-cot.xsd>`_).
Finally, the map parameters **InfoMapMOCParams** can optionally be associated to the product.



Keywords (Primary HDU)
++++++++++++++++++++++

The primary HDU is expected to contain the following keywords, characterizing
important parameters of the input product:

#. **DATE-OBS**: start of observation with format 'yyyy-mm-ddThh:mm:ss.sss' [StringKeyword]
#. **DATE-END**: end of observation with format 'yyyy-mm-ddThh:mm:ss.sss' [StringKeyword]
#. **TELESCOP**: name of the telescope [StringKeyword]
#. **INSTRUME**: name of the instrument [StringKeyword]
#. **FILTER**: name of the filter [StringKeyword]
#. **FILTLST**: selection of filter if intersection of multiple footprints [StringKeyword]
#. **TILEID**: identifier of the MER Tile processed (-1 if multiple Tiles) [IntegerKeyword]
#. **LISTID**: identifier of a MER list of tiles product (-1 if single Tile) [StringKeyword]
#. **NSIDE_WK**: Nside parameter used for frame->HEALPix [StringKeyword]
#. **INFO**: Information collected in the maps, e.g. "Noise", "PSF" [StringKeyword]
#. **STATS**: statiscts collected - e.g. RMS, median, max [StringKeyword]

   and basic software parameters:

#. **SOFTNAME**: name of software used [StringKeyword]
#. **SOFTVERS**: version of software used  [StringKeyword]

Partial MOC Footprint Table (First Extension, Binary Table)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The following keywords are used to describe what MOC conventions are followed:

#. **TTYPE1**  (= 'UNIQ') [StringKeyword]
#. **TFORM1**  (= 'K') [StringKeyword]
#. **TTYPE2**  (= 'WEIGHT') [StringKeyword]
#. **TFORM2**  (= 'E') [StringKeyword]
#. **PIXTYPE** (= 'HEALPIX') [StringKeyword]
#. **ORDERING** (= 'NUNIQ') [StringKeyword]
#. **COORDSYS** (= 'C'=celestial, 'E'=ecliptic or 'G'=galactic) [StringKeyword]
#. **MOCORDER** (best HEALPix order) [IntegerKeyword]
#. **MOCTYPE** [StringKeyword]
#. **DATE**  [StringKeyword]
#. **EXTNAME** (= 'INFO_MAP') [StringKeyword]


The table is then expected to contain the following columns:

#. **UNIQ**: index of pixel [K, int64]
#. **WEIGHT**: (floating-point) weight associated to pixel indicating the value of the instrumental
   or environmental parameter collected  [E, float32]
