IMB-FITS version 2.13

For single pixel receiver, the IMB-FITS data format provides the following FITS extensions:

  1. Primary: general description of the observation
  2. IMBF-scan: scan description (source, antenna offsets, etc)
  3. IMBF-frontend: frontend description (which receiver was connected, etc)
  4. 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):
  1. IMBF-backendFTS: provides the data dumps through time,
  2. IMBF-antenna: provides the antenna position through time at slow and fast rates.
  3. 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
