NAME¶
xsh_wavecal - Compute arclines tilt and instrument resolution
SYNOPSIS¶
esorex xsh_wavecal [OPTIONS] FILE.sof
DESCRIPTION¶
This recipe detects and follow arc lines in a fully illuminated slit frame.
Input Frames:
Raw frame (Tag = ARC_SLIT_arm)
Arc Line List (Tag = ARC_LINE_LIST_arm)
Master Bias (Tag = MASTER_BIAS_arm)
[OPTIONAL] Master Dark (Tag = MASTER_DARK_arm)
Order Table (Tag = ORDER_TABLE_EDGES_arm)
[poly mode] Wave Solution (Tag = WAVE_TAB_2D_arm)
[poly mode] Theoretical Map (Tag = THEO_TAB_spec_arm, spec=SING/IFU)
[physical model mode] Model cfg tab (Tag = XSH_MOD_CFG_TAB_arm)
- [OPTIONAL] A non-linear badpixel map (Tag = BP_MAP_NL_arm)
- [OPTIONAL] A reference badpixel map (Tag = BP_MAP_RP_arm)
[OPTIONAL-To compute spectral resolution] Dispersion Table Frame (Tag =
DISP_TAB_arm) Prepare PRE structures.
Subtract the master Dark (UVB, VIS and NIR) Substract the master Bias (UVB and VIS) Divide by Flat.
Detect and follow arc lines.
Products:
Wavelength solution, PRO.CATG = WAVE_TAB_ARC_SLIT_arm [if poly mode]
Linetilt list, PRO.CATG = TILT_TAB_SLIT_arm
Residuals table, PRO.CATG = RESID_TAB_GOOD_LINES_arm
Wave Map, PRO.CATG = WAVE_MAP_arm [if model-wavemap-compute=TRUE]
In case of IFU mode cdata previous producs repat for each IFU slices
Arc frame, Bias subtracted in PRE format, PRO.CATG = ARC_BIAS_SUBTRACT_arm
If arm=UVB/VIS and PRO.CATG=ARC_NIR_ON if arm=NIR
Arc frame, Bias subtracted, FLAT-FIELDED, PRO.CATG =
WAVECAL_FLATFIELDED_arm
OPTIONS¶
- --keep-temp <str>
- If ´no´, temporary files are deleted. (str; default: ´no´). The full name of this option for the EsoRex configuration file is xsh.xsh_wavecal.keep-temp [default = no].
- --debug-level <str>
- 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_wavecal.debug-level [default = none].
- --time-stamp <bool>
- Add timestamp to product file name. (bool; default: False). The full name of this option for the EsoRex configuration file is xsh.xsh_wavecal.time-stamp [default = False].
- --decode-bp <int>
- 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_wavecal.decode-bp [default = 2144337919].
- --pre-overscan-corr <int>
- 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_wavecal.pre-overscan-corr [default = 1].
- --followarclines-search-window-half-size <int>
- Half window size (HWS) in pixels (Y axis) of search window for each line. (int; default: 13). The full name of this option for the EsoRex configuration file is xsh.xsh_wavecal.followarclines-search-window-half-size [default = 13].
- --followarclines-order-edges-mask <int>
- Nb of pixels suppressed (X) from edges of search window. (int; default: 3). The full name of this option for the EsoRex configuration file is xsh.xsh_wavecal.followarclines-order-edges-mask [default = 3].
- --followarclines-min-sn <float>
