SYNOPSIS¶

esorex xsh_lingain [OPTIONS] FILE.sof

DESCRIPTION¶

This recipe computes detector linearity coefficients and gain Input Frames :
arm = UVB-VIS:
- A set of n RAW linearity frames (Format=RAW, n >=8, Tag = LINEARITY_arm_ON)
- A set of n RAW bias frames (Format=RAW, n >=1, Tag = LINEARITY_arm_OFF)
arm = NIR:
- A set of n RAW linearity on frames (Format=RAW, n >=8, Tag = LINEARITY_arm_ON)
- A set of n RAW linearity off frames (Format=RAW, n >=8, Tag = LINEARITY_arm_OFF)
