NAME

naco_spc_wavecal - Wavelength calibration using arc lamps

SYNOPSIS

esorex naco_spc_wavecal [OPTIONS] FILE.sof

DESCRIPTION

naco_spc_wavecal -- NACO spectrocopy wavelength calibration from lamp images. The files listed in the Set Of Frames (sof-file) must be tagged: NACO-raw-file.fits CAL_ARC_SPEC NACO-spectrum-model.fits SPC_MODEL . The input frames are split into groups with identical values of ´ESO DET DIT´, ´ESO INS OPTI1 ID´, ´ESO INS CWLEN´ and ´ESO SEQ SPECMODE´. Furthermore, each input frame must have a value of ESO INS LAMP1 ST that is false for off-frames and true for on-frames. Products: ARC_MAP: Primary HDU with the wavelength map, i.e. the pixel values are wave‐ lengths. The first extension is a single-row table with the polynomial coefficients of the 2D dispersion relation, lambda = P(x, y). ARC_IMAGE: Primary HDU with the difference image of the lamp-on and -off image. The first extension is the distortion corrected image, were all the arc-lines are straight. The dis‐ persion in the distortion corrected image is given by the central dispersion, lambda = P(512.5, y).

OPTIONS

--plot <long> The recipe can produce a number of predefined plots. Zero means that none of the plots are produced, while increasing values (e.g. 1 or 2) increases the number of plots produced. If the plotting fails a warning is produced, and the recipe contin‐ ues. The default behaviour of the plotting is to use gnuplot (with option -per‐ sist). The recipe currently produces 1D-plots using gnuplot commands. The recipe user can control the actual plotting-command used by the recipe to create the plot by setting the environment variable CPL_PLOTTER. Currently, if CPL_PLOTTER is set it must contain the string ´gnuplot´. Setting it to ´cat > my_gnuplot_$$.txt´ causes a number of ASCII-files to be created, which each produce a plot when given as standard input to gnuplot (e.g. later or on a different computer). A finer con‐ trol of the plotting options can be obtained by writing an executable script, e.g. my_gnuplot.pl, that executes gnuplot after setting the desired gnuplot options (e.g. set terminal pslatex color) and then setting CPL_PLOTTER to my_gnuplot.pl. The predefined plots include plotting of images. Images can be plotted not only with gnuplot, but also using the pnm format. This is controlled with the environ‐ ment variable CPL_IMAGER. If CPL_IMAGER is set to a string that does not contain the word gnuplot, the recipe will generate the plot in pnm format. E.g. setting CPL_IMAGER to ´display - &´ will produce a gray-scale image using the image viewer display. (long; default: 0). The full name of this option for the EsoRex configura‐ tion file is naco.naco_spc_wavecal.plot [default = 0]. --force <bool> Force the computation (bool; default: False). The full name of this option for the EsoRex configuration file is naco.naco_spc_wavecal.force [default = False]. 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.
