DATA section

There is one DATA section per frontend-backend combination. The following list is for frontend-backend combination 1 (the corresponding structure names for combination 2 were DATA2%HEADER and DATA2%DATA, and so on). Data associated parameters are interpolated from the monitor data (next section) at the MIDTIME timestamp of the backend data.


DATA1%HEADER S
DATA1%HEADER%CHANNELS I number of channels (for concatenated basebands)
DATA1%HEADER%OBSTATUS C*10 Observation o.k. ? (OK/ABORT)
DATA1%HEADER%DPBLOCK L Data blocking ?
DATA1%HEADER%OBSTYPE C*1 observation type (CAL, REF, ON, HOT, COLD, SKY)
DATA1%HEADER%LST D s Local apparent sidereal time (obs. start)
DATA1%HEADER%DATE_OBS C*23 observation start in TIMESYS system
DATA1%HEADER%OBSNUM I observation number
DATA1%HEADER%SCANNUM I scan number
DATA1%HEADER%FEBE C*17 frontend-backend identification
