Calibration Access and Data Handbook

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).
