Calibration Access and Data Handbook

Description

This CCF contains the fixed-offset vector tables for each CCD and each mode, as well as dark frame images of each of the 7 CCDs.

The CCF contains the following 12 extension tables:

OFFSET_CCD1 :

Accessed by :

• CAL_getMOSoffsets(): Routine to retrieve the row and column offsets for CCD 1 as given in the table.

Attributes:

None.

Columns:

MODE_ID :

numeric ID of the mode.

COL_X0 :

scalar value; column start in PIXCOORD0 coordinates for that mode

ROW_Y0 :

scalar value; row start in PIXCOORD0 coordinates for that mode

ROW_LEN :

row length in pixels for that mode

COL_LEN :

column length in pixel for that mode

ROW_OFFSET :

vector column (type I) length 610 with ADC offset values: one per column.

COLUMN_OFFSET :

vector column (type I) length 602 with ADC offset values: one per row.

OFFSET_CCD2...7 :

same as for OFFSET_CCD1 for CCD2 to 7.(see above).

DARKFRAME_CCD1 :

Accessed by :

• CAL_getMOSdarkFrameMap(): Retrieves full 600x600 dark frame array from CCF (in PIXCOOR1 coordinates)

Attributes:

None.

Columns:

DARKFRAME_CCD2...7 :

same as for DARKFRAME_CCD1 for CCD2 to 7.(see above).
