SHE

Detailed description of the data product¶

Data product containing a per-object broadband PSF, as output of the SHE_PSFToolkit software, for a catalogue of sources.

Stores each PSF image as a FITS file containing 3 HDUs NxN array (size set by user on runtime), as well as meta-data linking to object in question. The FITS file is in an XML container, which also stores the ExposureProductID and ObservationID linking to the VIS input file that the postage stamp is created from. The pixel size is set by the user.

The FITS output file will contain the following information:

HDUs

“Primary”: Header only HDU

#. “PSFC”: Catalogue containing additional information for PSF determination for object For each PSF defined in the PSFC there are the following HDUs #. “BPSF”: Bulge PSF images (as postage stamps) #. “DPSF”: Disk PSF images (as postage stamps)

Primary¶

$PrintPrimaryHeader fit/euc-she.xml she.psfModelImage

PSFC¶

A catalogue of the model PSFs contained within the product. This contains the OBJECT_ID, HDU indices of the disk and bulge PSFs, positional information for both the VIS image and the PSF cutout, and some statistical information about the PSF model.
