xsh_orderpos (7)

esorex xsh_orderpos [OPTIONS] FILE.sof

This recipe creates the orders centre traces table.

Input Frames for UVB and VIS:

  Raw file (Tag = ORDERDEF_arm_D2)
  Master Dark (Tag = MASTER_DARK_arm)
  Master Bias (Tag = MASTER_BIAS_arm)

Input Frames for NIR:

  Raw file ON(Tag = ORDERDEF_NIR_ON)
  Raw file OFF(Tag = ORDERDEF_NIR_OFF)

Input Frames for all arms

  Guess order table (Tag = ORDER_TAB_GUESS_arm)
  Spectral format table (Tag = SPECTRAL_FORMAT_TAB_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)

Prepare PRE structures.

For NIR, subtract NIR-OFF from NIR-ON.

For UVB and NIR, Substract the master Bias and master dark.

Detect Orders and calculate the order table.

The final products are:

   An updated Order Table, PRO.CATG=ORDER_TABLE_CENTR_arm.

   A order trace residuals Table, PRO.CATG=ORDERPOS_RESID_TAB_arm.

   The order pos frame bias subtracted, PRO.CATG=ORDERDEF_ON_arm.

Minimal fractions of points accepted / total in sigma clippingduring order trace polynomial fit (float; default: 0.4). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-clip-frac [default = 0.4].

Note that it is possible to create a configuration file containing these options, along with suitable default values. Please refer to the details provided by the 'esorex --help' command.
