For single pixel receiver, the IMB-FITS data format provides the
following FITS extensions:
- Primary: general description of the observation
- IMBF-scan: scan description (source, antenna offsets, etc)
- IMBF-frontend: frontend description (which receiver was
connected, etc)
- IMBF-backend: backend configuration i.e. how the chunks
translate to sky frequency.
Then, the 3 following extensions are repeated for each subscan
(example with FTS backend):
- IMBF-backendFTS: provides the data dumps through time,
- IMBF-antenna: provides the antenna position through time
at slow and fast rates.
- IMBF-subreflector: not used by MRTCAL.
Each of these extensions are detailed below from an example scan,
showing the output of the command MDUMP8.1
