DataProductElementsEnd Detailed Description of the Data Product ________________________________________ .. DetailedDescStart This output product collects environmental/instrumental information for a filter of an instrument. This output product is composed of **InfoMapHealpix**, a container with a FITS file in partial HEALPix format (of type le3.id.vmpz.healpixinfomap) collecting environmental/instrumental information for a filter of an instrument. 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 `_). Finally, the map parameters **InfoMapHealpixParams** can optionally be associated to the product. +------------------------------+-----------------------------------+-------------------------------------+ | Measurements | Subtype (XML) / INFO (FITS) field | Data source | +==============================+===================================+=====================================+ | Tile Index | Tile | MER Tile | +------------------------------+-----------------------------------+-------------------------------------+ | Solar Aspect Angle | SAA | MER Bks Mosaic | +------------------------------+-----------------------------------+-------------------------------------+ | Alpha Angle | AA | MER Bks Mosaic | +------------------------------+-----------------------------------+-------------------------------------+ | Beta Angle | BA | MER Bks Mosaic | +------------------------------+-----------------------------------+-------------------------------------+ | Exposures | Exposures | MER Bks Mosaic | +------------------------------+-----------------------------------+-------------------------------------+ | Noise (RMS) | Noise | MER Bks Mosaic | +------------------------------+-----------------------------------+-------------------------------------+ | PSF FWHM | PSF | MER Bks Mosaic | +------------------------------+-----------------------------------+-------------------------------------+ | Galactic Extinction / band | GalacticExtinction | from Plank E(B-V) map, see :sup:`1` | +------------------------------+-----------------------------------+-------------------------------------+ | Zodiacal Light / band | ZodiacalLight | see :sup:`1` | +------------------------------+-----------------------------------+-------------------------------------+ | Galaxy Number Density | GalaxyNumberDensity | CatRed catalogs | +------------------------------+-----------------------------------+-------------------------------------+ | PhotoZ Weight | GalaxyPhZWeight | CatRed catalogs | +------------------------------+-----------------------------------+-------------------------------------+ | PHZ70 Mean / RMS / Std | GalaxyRelPhZSeventy{Mean,Rms,Std} | CatRed catalogs | +------------------------------+-----------------------------------+-------------------------------------+ | Star Number Density | StarNumberDensity | Gaia catalogs | +------------------------------+-----------------------------------+-------------------------------------+ | Star FLUX_G Mean / RMS / Std | StarBrightness{Mean,Rms,Std} | Gaia catalogs | +------------------------------+-----------------------------------+-------------------------------------+ :sup:`1`: `Euclid preparation: I.
