xsh_mbias(7) 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)
