XSH_ORDERPOS(7) xshoo recipes XSH_ORDERPOS(7)

NAME

xsh_orderpos - Create the orders centre traces table file

SYNOPSIS

esorex xsh_orderpos [OPTIONS] FILE.sof

DESCRIPTION

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.

OPTIONS

If ´no´, temporary files are deleted. (str; default: ´no´). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.keep-temp [default = no].
Additional xshooter debug level. One of ´none´, ´low´, ´medium´, ´high´ (str; default: ´none´). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.debug-level [default = none].
Add timestamp to product file name. (bool; default: False). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.time-stamp [default = False].
Integer representation of the bits to be considered bad when decoding the bad pixel mask pixel values. Most frequent codes relevant for the user: 0: good pixel, 8: pick-up noise, 16: cosmic-ray removed, 32: cosmic-ray unremoved, 128: calibration file defect, 256: hot pixel, 512: dark pixel, 4096: A/D converted saturation, 32768: non linear pixel, 1048576: extrapolated flux in NIR, 4194304: Interpolated flux during extraction. (int; default: 2144337919). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.decode-bp [default = 2144337919].
pre-overscan correction. 0: no correction 1: mean overscan correction 2: mean prescan correction 3: (mean pre+mean overscan)/2 correction (int; default: 1). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.pre-overscan-corr [default = 1].
Half window size in pixels for the 1D box to search for the maximum in the cross-dispersion profile (int; default: 5). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-search-win-hsize [default = 5].
Half window size for the running median box during the search for the maximum in the cross-dispersion profile (int; default: 0). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-running-win-hsize [default = 0].
Half window size for the fit of the cross-dispersion profile (int; default: 5). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-fit-win-hsize [default = 5].
Threshold factor applied to check that the flux at the fitted peak is higher than error. (float; default: 0.0). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-center-thresh-fac [default = 0.0].
Step in Y for order centroid detection (int; default: 1). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-ordertab-step-y [default = 1].
Degree in Y in the polynomial order tracing X=f(Y) (int; default: 5). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-ordertab-deg-y [default = 5].
Maximum allowed residual (before kappa-sigma clip) (float; default: 0.5). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-clip-res-max [default = 0.5].
Kappa value in sigma clipping during order trace polynomial fit (float; default: 5.0). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-clip-sigma [default = 5.0].
Number of iterations in sigma clipping during order trace polynomial fit (int; default: 5). The full name of this option for the EsoRex configuration file is xsh.xsh_orderpos.detectcontinuum-clip-niter [default = 5].
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.
