.. _EN_Appendix-C-output-files: ************************* 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** :download:`pdf `
