========================================
.. DetailedDescStart

This output product is a file describing the footprint of the survey in mangle format, for a given band
out of the N observed bands (Euclid/EXT).
It includes a base mangle mask  described as `genericVectorMask <https://gitlab.euclid-sgs.uk/ST-DM/ST_DataModel/raw/fsureau/features/DMLE3_VMPZ_ID/dictionary/bas/msk/euc-test-msk.xsd>`_ file describing the footprint for the survey in partial HEALPix format,
for a given observed band/instrument (Euclid/EXT), and a raw description with polygons of the envelope of the sky covered is added as well to ease future queries on the product (see `spatialFootprint <https://gitlab.euclid-sgs.uk/ST-DM/ST_DataModel/blob/develop/dictionary/bas/cot/euc-test-cot.xsd>`_).

The weights associated to the mangle polygon in the ascii file are in between 0 and 1, describing the fraction of pixel observed
with 1: not in footprint, not observed and 0: in footprint, fully observed.
Associated to the file is a xml descriptor with parameters:

#. **DATE-OBS**: start of observation with format 'yyyy-mm-ddThh:mm:ss.sss'.
#. **DATE-END**: end of observation with format 'yyyy-mm-ddThh:mm:ss.sss'.
#. **INSTRUM**: name of the instrument
#. **TELESCOP**: name of the telescope
#. **FILTER**: name of the filter
#. **TILEINDEX**: identifier of the MER Tile (-1 if multiple Tiles)
#. **SKYPATCH_ID**: identifier of the skyPatch if merging multiple MER Tiles (TBD)

and basic software parameters:

#. **CREATOR**: software used to create the product
#. **VERSION**: version of software
