It must be called after the kmo\_flat recipe, which generates the two spatial calibration frames needed in this recipe. As input a lamp-on frame, a lamp-off frame, the spatial calibration frames and the list with the reference arclines are required. An additional output frame is the resampled image of the reconstructed arc frame. All slitlets of all IFUs are aligned one next to the other. This frame serves for quality control. One can immediately see if the calibration was successful. The lists of reference arclines are supposed to contain the lines for both available calibration arc-lamps, i.e. Argon and Neon. The list is supposed to be a F2L KMOS FITS file with three columns:\ 1\. Reference wavelength\ 2\. Relative strength\ 3\. String either containing “Ar” or “Ne” The recipe extracts, based on the header keywords, either the applying argon and/or neon emission lines. Below are the plots of the emission lines for both argon and neon. The marked lines are the ones used for wavelength calibration. Furthermore frames can be provided for several rotator angles. In this case the resulting calibration frames for each detector are repeatedly saved as extension for every angle. ### BASIC PARAMETERS \--order The polynomial order to use for the fit of the wavelength solution. 0: (default) The appropriate order is chosen automatically depending on the waveband (4 for IZ band, 5 for HK, 6 for the others) ### ADVANCED PARAMETERS \--b\_samples The number of samples in spectral direction for the reconstructed cube. Ideally this number should be greater than 2048, the detector size. \--suppress\_extension If set to TRUE, the arbitrary filename extensions are supressed. If multiple products with the same category are produced, they will be numered consecutively starting from 0. \--lines\_estimation If set to TRUE, the lines estimation method is used Input files: DO category Type Explanation Required #Frames\ \----------- ----- ----------- -------- -------\ ARC\_ON RAW Arclamp-on exposure Y \>=1\ ARC\_OFF RAW Arclamp-off exposure Y 1\ XCAL F2D x calibration frame Y 1\ YCAL F2D y calibration frame Y 1\ ARC\_LIST F2L List of arclines Y 1\ FLAT\_EDGE F2L Fitted edge parameters Y 1\ REF\_LINES F2L Reference line table Y 1\ WAVE\_BAND F2L Table with start-/end-wavelengths Y 1 Output files: DO category Type Explanation\ \----------- ----- -----------\ LCAL F2D Wavelength calibration frame\ (3 Extensions)\ DET\_IMG\_WAVE F2D reconstructed arclamp-on exposure\ (4 extensions: 3 detector images + \ the arclines list table) ## OPTIONS - **--order** *\* The fitting polynomial order used for the wavelength solution. By default, 4 for IZ band, 5 for HK, 6 for the others (int; default: 0). The full name of this option for the EsoRex configuration file is **kmos.kmos\_wave\_cal.order** \[default = *0*\]. - **--suppress\_extension** *\* Suppress arbitrary filename extension (bool; default: False). The full name of this option for the EsoRex configuration file is **kmos.kmos\_wave\_cal.suppress\_extension** \[default = *False*\]. - **--lines\_estimation** *\* Trigger lines estimation method (bool; default: False). The full name of this option for the EsoRex configuration file is **kmos.kmos\_wave\_cal.lines\_estimation** \[default = *False*\]. - **--b\_samples** *\* The number of samples in wavelength for the reconstructed cube (int; default: 2048). The full name of this option for the EsoRex configuration file is **kmos.kmos\_wave\_cal.b\_samples** \[default = *2048*\]. - **--det** *\* Only reduce the specified detector (int; default: 0). The full name of this option for the EsoRex configuration file is **kmos.kmos\_wave\_cal.detector** \[default = *0*\]. - **--angle** *\* Only reduce the specified angle (float; default: 370.0). The full name of this option for the EsoRex configuration file is **kmos.kmos\_wave\_cal.angle** \[default = *370.0*\]. Note that it is possible to create a configuration file containing these options, along with suitable default values.
