Calibration Access and Data Handbook

Description

The file contains median maps, noise maps and an offset correction table used in low energy noise reduction of the PN.

The CCF contains the following tables:

NOISE_MAP_INDEX

An index which gives the name of the extension containing the correct noise map for a given mode, ccd and rawx value.

Attributes:

None.

Columns:

MODE:

The observing mode

CCD:

The CCD number

RAWX:

X-range specification

POINTER:

Name of the noise map extension

EXPOSURE:

Exposure time of the map (secs)

MEDIAN_MAP_INDEX

An index to the median map extensions.

Attributes:

None.

Columns:

MODE:

The observing mode

CCD:

The CCD number

POINTER:

Name of the median map extension
