DetailedDescStart 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 :ref:`NIRStackedFrame` 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. .. _NIR_stacked_frame_catalog: .. figure:: ../figures/nirStackedCatalog.png :scale: 100 % :align: center :figclass: align-center : Graphical representaton of ``Data`` section structure for **DpdNirStackedFrameCatalog** The main elements inside the *Data* section are: * **SpatialCoverage** * **CatalogDescription** * **SpectralCoverage** * **CatalogDescription** * **ObservationId**: Observation Id of origin stacked image * **DataStorage**: Element that links to a FITS file containing the Stacked image FITS file * **TargetPointing**: Coordinates of target pointing * **QualityParams** (optional): Data Quality Parameters * **ObjectCount**: Number of object in the catalog * **MagAper**: Basic statistics for Magnitude APER extraction (mag) * **MagAuto**: Basic statistics for Magnitude AUTO extraction (mag) * **MagPSF**: Basic statistics for Magnitude PSF extraction (mag) * **Bright**: Basic statistics on errors for brighter sources * **Faint**: Basic statistics on errors for fainter sources Scientific FITS File ^^^^^^^^^^^^^^^^^^^^ ..
