NAME
xsh_mbias - Create the master bias frame
SYNOPSIS
esorex xsh_mbias [OPTIONS] FILE.sof
DESCRIPTION
This recipe creates a master bias frame by computing the median of all input bias frames.
Input Frames :
- A set of n RAW frames (Format=RAW, n >=3, Tag = BIAS_arm)
- [OPTIONAL] A map of non linear bad pixels (Format=QUP, Tag = BP_MAP_NL_arm)
- [OPTIONAL] A map of reference bad pixels (Format = QUP,RAW, Tag = BP_MAP_RP_arm) Products :
- A master bias frame (Format=PRE, PRO.CATG = MASTER_BIAS_arm)
