This product is proposed for inclusion in the SAS: maybe

These products partition the sky in a semi-regular grid for MER processing.
It could be useful for scientists to have access to this tiling.

Detailed Description of the Data Product
________________________________________
.. DetailedDescStart

This is an input product to the MER :term:`Pipeline`. Tiles partition the sky
in a semi-regular grid. The MER pipeline is run in each tile and their output
products follow the tile spatial footprint.

The main elements inside this product are:

* **TileUseCase**: The use case for which the tile has been defined (e.g. WIDE,
  DEEP, CALIBRATION).
* **TileFlavour**: The tile falvour (e.g. NORMAL, BORDER, SPECIAL)
* **TileIndex**: The tile index.
* **Version**: The tiling release version.
* **OuterNUNIQIndex**: The outer tile area MOC Healpix indices.
* **InnerNUNIQIndex**: The inner tile area MOC Healpix indices.
* **OuterSpatialFootprint**: The outer tile area spatial footprint. The outer
  area of a given tile overlaps with other tiles.
* **InnerSpatialFootprint**: The inner tile area spatial footprint. The inner
  area of a given tile does not overlap with other tiles.
* **ExtendedObjects** (optional): List of extended objects falling inside the
  tile area.
