Instrument modes

The following is an example (for EMOS) of the instrument mode information that odfingest can derive with the help of the calibration data base.

MODE = PrimePartialW2 / Instrument configuration 
CALIBRATION_MODE_1 = PrimePartialW2 / Mode used to calibrate events from CCD 1
CALIBRATION_MODE_2 = PrimeFullWindow / Mode used to calibrate events from CCD 2
CALIBRATION_MODE_3 = PrimeFullWindow / Mode used to calibrate events from CCD 3
CALIBRATION_MODE_4 = PrimeFullWindow / Mode used to calibrate events from CCD 4
CALIBRATION_MODE_5 = PrimeFullWindow / Mode used to calibrate events from CCD 5
CALIBRATION_MODE_6 = PrimeFullWindow / Mode used to calibrate events from CCD 6
CALIBRATION_MODE_7 = PrimeFullWindow / Mode used to calibrate events from CCD 7
DATA_MODE_1 = Imaging / Data mode for CCD 1
DATA_MODE_2 = Imaging / Data mode for CCD 2
DATA_MODE_3 = Imaging / Data mode for CCD 3
DATA_MODE_4 = Imaging / Data mode for CCD 4
DATA_MODE_5 = Imaging / Data mode for CCD 5
DATA_MODE_6 = Imaging / Data mode for CCD 6
DATA_MODE_7 = Imaging / Data mode for CCD 7

The MODE parameter describes the instrument configuration as determined by the cal.

The CALIBRATION_MODE_n parameters describe the CCD mode that the cal would use to calibrate the science data for the n-th CCD (or window, in the case of OM).

The DATA_MODE_n parameters indicate the data mode (determined by the oal) the n-th CCD was in during the exposure.

The example above says that the 7 CCDs were operated in imaging mode. The detailed configuration (this determines what calibration data and algorithms to apply) of CCD 1 correspond to the mode PrimePartialW2, while the other 6 CCDs were opearated in PrimeFullWindow mode. The overall instrument configuration for this exposure was PrimePartialW2.

The MODE is set to UNDEFINED if it cannot be cannot be determined, or if it does not make sense for a certain DATA_MODE (for instance there is no calibration mode associated with the RGS diagnostic images).
