Observational modes

source: 

For STIX there is only 1 data acquisition mode. Acquired science data are selected on-board autonomously (~500bps) or selected on-ground and retrieved via TC (~100bps).

STIX Normal Mode - TC-requested data~1001.45 (if acquiring full orbit)
STIX LL~500.7 (if acquiring full orbit)
STIX HK~500.7 (if acquiring full orbit)

Engineering modes & power consumption
