# Appendix C - Output files¶

The system at present allows the user to write the output data, coming from the integrated backends, in two different formats: FITS and MBFITS. The former is a substantially standard FITS, carrying the data and a load of ancillary information inside several extensions. A FITS is produced for every subscan composing the observation.

MBFITS is a more complex format, not yet fully implemented and whose writer component is still under testing. Each MBFITS contains the whole scan, and subscans are hierarchically organized inside its structure.

Details on both formats are provided in this separate manual pdf
