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)
- [OPTIONAL] a static bad pixel map (PRO.CATG=BP_MAP_RP_arm)
Note: on and off frames are taken in pairs sequence: OFF-ON-ON-OFF,
at least 16 frames.
