# 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 `MDUMP`8.1
