TABLE  SpecFrameFitsKey

List of FITS keywords extracted from the headers of SpecFrames.

This table lists all the FITS keywords in all the SpecFrames ingested into
the archive. It is not anticipated that these keywords will be accessed
often, since the most useful metadata keys are present as attributes in the
SpecFrame table. If, however, information from this table is required, note
that all data are stored as FITS key character strings so use of the built-in
SQL function CAST is required to perform operations within expressions on these
attributes.


Required constraints:
  • Primary key is (specFrameID, extNum, name)
  • (specFrameID) references SpecFrame(specFrameID)
