Astro::FITS::HdrTrans::SCUBA2 - JCMT SCUBA-2 translations
Converts information contained in SCUBA-2 FITS headers to and from generic headers. See Astro::FITS::HdrTrans for a list of generic headers.
The name of the instrument required to match (case insensitively) against the INSTRUME/INSTRUMENT keyword to allow this class to translate the specified headers. Called by the default can_translate method.
can_translate
$inst = $class->this_instrument();
Returns "SCUBA-2".
These methods are more complicated than a simple mapping. We have to provide both from- and to-FITS conversions All these routines are methods and the to_ routines all take a reference to a hash and return the translated value (a many-to-one mapping) The from_ methods take a reference to a generic hash and return a translated hash (sometimes these are many-to-many)
If Observation type is SCIENCE, return the sample mode, else return the sample mode and observation type. For example, "STARE", "SCAN", "SCAN_POINTING".
Do not currently take into account polarimeter or FTS.
Fix up recipes that were incorrect in the early years of the observing tool.
Converts SASSy survey data to use the SASSy recipe.
Determine if POL-2 is in the beam, based on the INBEAM header.
Attempt to recreate the INBEAM header. Since this also depends on FTS-2, use the _reconstruct_INBEAM method.
Determine if FTS-2 is in the beam, based on the INBEAM header.
Attempt to recreate the INBEAM header. Since this also depends on POL-2, use the _reconstruct_INBEAM method.
Since the INBEAM header becomes multiple generic headers, we need to look at them all to reconstruct it. In order to work within the confines of the Astro::FITS::HdrTrans::Base::translate_to_FITS method, we need to work on a per-generic header basis. This internal method can then be used for the "from_" method for each of these. It will end up returning the same INBEAM header each time -- the versions generated from different generic headers will overwrite eachother in the Base translate_to_FITS method but that shouldn't be a problem.
Note that the INBEAM header may not be reconstructed exactly. For example it will just include the short form "pol" even if it would originally have included specific POL-2 components instead.
