Detailed description of the data product¶
An XML data product containing calibrated shear measurements fits tables from all three production methods. The difference between SHEFinalMeasurements and SHEMeasurements is that SHEFinalMeasurements have been calibrated. This product will contain the following 3 catalog container objects, each pointing to a fits binary table:
lensMcShearMeasurements
MetaCalShearMeasurements
MomentsMlShearMeasurements
All of these are optional, but at least one must exist. In each case, 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.
Output Catalog¶
The output xml product points to 3 FITS binary catalogs. These fits catalogs will contain the following header keywords and columns:
