| Abstract: |
We describe a new archive of legacy data from the United Kingdom
Infrared Telescope (UKIRT) at the Canadian Astronomy Data Centre (CADC)
containing all available data from the Cassegrain instruments. The
desire was to archive the raw data in as close to the original format as
possible, so where the data followed our current convention of having a
single data file per observation, it was archived without alteration,
except for minor fixes to headers of data in FITS format to allow it to
pass fitsverify and be accepted by CADC. Some of the older
data comprised multiple integrations in separate files per observation,
stored in either Starlink NDF or Figaro DST format. These were placed
inside HDS container files, and DST files were rearranged into NDF
format. The describing the observations is ingested into the
CAOM-2 repository via an intermediate MongoDB header database,
which will also be used to guide the ORAC-DR pipeline in
generating reduced data products. |
