.TH MUSE_EXP_ALIGN "7" "1.6.2" "muse_exp_align" "muse recipes" .SH NAME muse_exp_align \- Create a coordinate offset table to be used to align exposures during exposure combination. .SH SYNOPSIS esorex .B muse_exp_align [OPTIONS] FILE.sof .SH DESCRIPTION Compute the coordinate offset for each input field\-of\-view image with respect to a reference. The created list of coordinate offsets can then be used in muse_exp_combine as the field coordinate offsets to properly align the exposures during their combination. .SH OPTIONS .TP \fB\-\-rsearch\fR \fI\fR Search radius (in arcsec) for each iteration of the offset computation. (str; default: \'30.,4.,2.,0.8\'). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.rsearch\fR [default = \fI30.,4.,2.,0.8\fR]. .TP \fB\-\-nbins\fR \fI\fR Number of bins to use for 2D histogram on the first iteration of the offset computation. (long; default: 60). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.nbins\fR [default = \fI60\fR]. .TP \fB\-\-weight\fR \fI\fR Use weighting. (bool; default: True). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.weight\fR [default = \fITrue\fR]. .TP \fB\-\-fwhm\fR \fI\fR FWHM in pixels of the convolution filter. (float; default: 5.0). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.fwhm\fR [default = \fI5.0\fR]. .TP \fB\-\-threshold\fR \fI\fR Initial intensity threshold for detecting point sources in sigma above background RMS. (float; default: 15.0). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.threshold\fR [default = \fI15.0\fR]. .TP \fB\-\-step\fR \fI\fR Increment/decrement of the threshold value in subsequent iterations. (float; default: 0.5). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.step\fR [default = \fI0.5\fR]. .TP \fB\-\-iterations\fR \fI\fR Maximum number of iterations used for detecting sources. (long; default: 100000). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.iterations\fR [default = \fI100000\fR]. .TP \fB\-\-srcmin\fR \fI\fR Minimum number of sources which must be found. (long; default: 5). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.srcmin\fR [default = \fI5\fR]. .TP \fB\-\-srcmax\fR \fI\fR Maximum number of sources which may be found. (long; default: 80). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.srcmax\fR [default = \fI80\fR]. .TP \fB\-\-roundmin\fR \fI\fR Lower limit of the allowed point\-source roundness. (float; default: \-1.0). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.roundmin\fR [default = \fI\-1.0\fR]. .TP \fB\-\-roundmax\fR \fI\fR Upper limit of the allowed point\-source roundness. (float; default: 1.0). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.roundmax\fR [default = \fI1.0\fR]. .TP \fB\-\-sharpmin\fR \fI\fR Lower limit of the allowed point\-source sharpness. (float; default: 0.2). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.sharpmin\fR [default = \fI0.2\fR]. .TP \fB\-\-sharpmax\fR \fI\fR Upper limit of the allowed point\-source sharpness. (float; default: 1.0). The full name of this option for the EsoRex configuration file is \fBmuse.muse_exp_align.sharpmax\fR [default = \fI1.0\fR]. .PP Note that it is possible to create a configuration file containing these options, along with suitable default values.
