Calibration Access and Data Handbook

Description

Describes the pn filter transmission vs energy. The CCF contains one extension of transmission values per filter, and one extension containing the common energy bins. The filter extensions include a region expression to cover cases where there are known spatial variations.

The CCF contains the following tables:

FILTER-THIN1:

Thin1 filter transmission values.

Attributes:

None.

Columns:

REGION:

The description of the region in which the transmission values are valid.

TRANSMISSION:

Variable length vector containing the transmission values corresponding to each energy bin datum.

FILTER-THIN2:

Thin2 filter transmission values.

Attributes:

None.

Columns:

REGION:

The description of the region in which the transmission values are valid.

TRANSMISSION:

Variable length vector containing the transmission values corresponding to each energy bin datum.

FILTER-MEDIUM:

Medium filter transmission values.

Attributes:

None.

Columns:

REGION:

The description of the region in which the transmission values are valid.

TRANSMISSION:

Variable length vector containing the transmission values corresponding to each energy bin datum.

FILTER-THICK:

Thick filter transmission values.

Attributes:

None.

Columns:

REGION:

The description of the region in which the transmission values are valid.

TRANSMISSION:

Variable length vector containing the transmission values corresponding to each energy bin datum.

FILTER-OPEN:

Open filter transmission values.

Attributes:

None.

Columns:

REGION:

The description of the region in which the transmission values are valid.
