Detailed Description of the Data Product¶

The DpdNirStackedFrameCatalog is one of the output of the NIR_ProcessField_Pipeline applied to wide survey observations and in general to “scientific” images (i.e. it could be executed also on Self Calibration images).

The catalog is extracted from NIR Stacked Frame images. A single catalog is, therefore, provided at the end of each NIR_ProcessField_Pipeline run.

The DpdNirStackedFrameCatalog data product contains the link to a FITS file.
