Description

The redistribution parameters for the MOS cameras.

The CCF contains the following tables:

CCD_REDISTRIBUTION-n
The redistribution parameters for the MOS detectors are given here per CCD. NB: The response of the MOS detectors has evolved as the satellite has aged. A separate REDIST file is available for each epoch where the response is seen to be different.
Attributes:
None.
Columns:
MODE_ID:
The observing mode.
REGION:
The central CCD of each MOS detector has developed a patch where the energy resolution is worse than the average. This column describes each region.
THRESHOLD
: The event cut-off threshold (eV).
GRADE:
The pattern type [1=singles (pattern 0 only); 2=singles,doubles,triples and quads (patterns 0-12)].
PARAM:
The redistribution parameters.
PHA_EBOUNDS
The energy bounds of PHA channels.
Attributes:
None.
Columns:
CHANNEL:
The PHA channel number.
E_MIN:
Minimum energy (eV).
E_MAX:
Maximum energy (eV).
BINNEDPI_EBOUNDS
The energy bounds of the PI channels, used to determine the equivalent energies of spectral channels in the redistribution matrix construction.
Attributes:
None.
Columns:
CHANNEL:
The PI channel number.
E_MIN:
Minimum energy (eV).
E_MAX:
Maximum energy (eV).
EBINS
The energy bins used when contructing the redistribution matrix.
Attributes:
None.
Columns:
CHANNEL:
The channel number.
E_MIN:
Minimum energy (eV).
E_MAX:
Maximum energy (eV).
