.TH NACO_IMG_CHECKFOCUS "7" "4.4.11" "naco_img_checkfocus" "naco recipes" .SH NAME naco_img_checkfocus \- Focus check recipe .SH SYNOPSIS esorex .B naco_img_checkfocus [OPTIONS] FILE.sof .SH 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. .PP .SH OPTIONS .TP \fB\-\-plot\fR \fI\fR 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 \fBnaco.naco_img_checkfocus.plot\fR [default = \fI0\fR]. .TP \fB\-\-star_r\fR \fI\fR The star radius [arcsecond] (float; default: 2.0). The full name of this option for the EsoRex configuration file is \fBnaco.naco_img_checkfocus.star_r\fR [default = \fI2.0\fR]. .TP \fB\-\-bg_r1\fR \fI\fR The internal radius of the background [arcsecond] (float; default: 2.0). The full name of this option for the EsoRex configuration file is \fBnaco.naco_img_checkfocus.bg_r1\fR [default = \fI2.0\fR]. .TP \fB\-\-bg_r2\fR \fI\fR The external radius of the background [arcsecond] (float; default: 3.0). The full name of this option for the EsoRex configuration file is \fBnaco.naco_img_checkfocus.bg_r2\fR [default = \fI3.0\fR]. .PP Note that it is possible to create a configuration file containing these options, along with suitable default values.
