### REDUCE section

The REDUCE section is not a part of the MBFITS raw-data format, and contains MIRA-internal flags describing the calibration history. There is one REDUCE section per frontend-backend combination, i.e. REDUCE1, REDUCE2, etc.

REDUCE1 | S |
REDUCE1%DESPIKE_DONE | L | Data despiked (yes/no) ?
REDUCE1%BASE_DONE | L | Baseline subtracted (yes/no) ?
REDUCE1%CALIBRATION_DONE | 4 I | Calibration done ?
|  | (1) Normalized by gainarray (yes /no) ?
|  | (2) Backend count rates (no) or temp. scale (yes) ?
|  | (3) Off signal subtracted (yes /no) ?
|  | (4) Cross correlation phases calibrated (yes /no) ?
