SYNOPSIS

esorex naco_img_checkfocus [OPTIONS] FILE.sof

DESCRIPTION

naco_img_checkfocus -- The focus checking recipe The Set Of Frames (sof-file) must specify at least four files and they must be tagged NACO-raw-file.fits TECH_FOCUS The first of the files is used as a dark frame.

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 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. (long; default: 0). The full name of this option for the EsoRex configuration file is naco.naco_img_checkfocus.plot [default = 0].

--star_r <float>

The star radius [arcsecond] (float; default: 2.0). The full name of this option for the EsoRex configuration file is naco.naco_img_checkfocus.star_r [default = 2.0].

--bg_r1 <float>

The internal radius of the background [arcsecond] (float; default: 2.0). The full name of this option for the EsoRex configuration file is naco.naco_img_checkfocus.bg_r1 [default = 2.0].

--bg_r2 <float>

The external radius of the background [arcsecond] (float; default: 3.0). The full name of this option for the EsoRex configuration file is naco.naco_img_checkfocus.bg_r2 [default = 3.0].

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.
