Proposed for inclusion in EAS/SAS |
This product is proposed for inclusion in the SAS: yes the Lens MC chains may be useful to scientists. |
Detailed description of the data product¶
An XML data product containing MCMC chains fits tables from the LensMC method produced along with SheLensMcMeasurements as outputs of the Lens Mc pipeline.
This product will contain the following catalogContainer object pointing to a fits binary table:
LensMcChains
Since the storage is a binary table, the table and its header will be stored in the first extension, with the primary HDU being a default, empty image.
Name of file:
EUC_SHE_LENSMC-CHAINS_TILE-[TILE_ID]_[YYYYMMDDThhmmss.s]Z_[VERSION].fits.gz
where TILE_ID is the ID of the tile used for this measurement, YYYYMMDDThhmmss.s is the time the product was created in UTC, and VERSION is the version number of the SHE pipeline used to create the data product.
