Calibration Access and Data Handbook

Description

One extension providing the list by instrument mode of important fixed parameters such as readout dead time, frame times, live times, window sizes, etc ... It allows to correct for mode dependent factors.

The CCF contains one table:

MODEPARAM:

table with characteristic parameters of the various observing modes, accessed by :

• CAL_getModeParameters():

UNDER_Y:

Row under scan in pixels.

OVER_Y:

Row over scan in pixels.

Columns:

MODE_ID:

numeric Mode identifier.

INTEGRATION_T:

Integration time (ms).

SHIFT_T:

Shift time (ms).

FRAME_T:

WINDOWX0:

X-coord. (PIXCOORD0) of lower left corner of readout window.

WINDOWY0:

Y-coord. (PIXCOORD0) of lower left corner of readout window.

WINDOWDX:
