Usage

Overview

naco_spc_combine -- NACO Combination of spectroscopic science data.

The files listed in the Set Of Frames (sof-file) must be tagged: NACO-raw-file.fits SPEC_NODDING or NACO-flat-file.fits MASTER_SPC_FLAT (optional).

For nodded frames (SPEC_NODDING) there must be an identical number of exposures on each side of the center, these pairs of nodded exposures should preferably be taken with one immediately after the other. More precisely, the i´th A-FRAME will be paired with the i´th B-frame

Options

--xtmax <int>

Stop the spectrum extraction at this column (int; default: 1024). The full name of this option for the EsoRex configuration file is naco.naco_spc_combine.extract_max [default = 1024].

--xtmin <int>

Start the spectrum extraction at this column (int; default: 1). The full name of this option for the EsoRex configuration file is naco.naco_spc_combine.extract_min [default = 1].

--save <int>

A positive value causes additional, intermediate products to be saved (int; default: 0). The full name of this option for the EsoRex configuration file is naco.naco_spc_combine.save [default = 0].

--plot <int>

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 continues. The default behaviour of the plotting is to use gnuplot (with option -persist). 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 control 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 environment 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. (int; default: 0). The full name of this option for the EsoRex configuration file is naco.naco_spc_combine.plot [default = 0].

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.
