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) (xsh_subtract_dark) Substract the master Bias (UVB and
VIS)(amodigli@pc014007$ vi xsh_wavecal_fail.sofxsh_substract_bias) 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
