SIAF

class jwst.lib.siafdb.SIAF(v2_ref, v3_ref, v3yangle, vparity, crpix1, crpix2, cdelt1, cdelt2, vertices_idl)

Bases: tuple

SIAF container.

The names should correspond to the names in the wcsinfo schema. It is populated by the SIAF values in the PRD database based on APERNAME and UseAfterDate and used to populate the keywords in Level1bModel data models.

Default values are set for the SIAF. Values which are needed by the pipeline are set to None, which triggers a ValueError if missing in the SIAF database. Quantities not used by the pipeline get a default value - FITS keywords and aperture vertices.
