They may also be wild cards, in such cases, they must be enclosed by double or single quotes, or they may be directory names. If both are directory names, all files in each of the directories will be included; if only one is a directory name, then the directory name will be prefixed to the file name(s) specified by the other argument. for example:: fitsdiff "*.fits" "/machine/data1" will compare all FITS files in the current directory to the corresponding files in the directory /machine/data1. s' If the two files are identical within the specified conditions, it will report "No difference is found." If the value(s) of -c and -k takes the form '@filename', list is in the text file 'filename', and each line in that text file contains one keyword. Example ------- fitsdiff -k filename,filtnam1 -n 5 -r 1.e-6 test1.fits test2 This command will compare files test1.fits and test2.fits, report maximum of 5 different pixels values per extension, only report data values larger than 1.e-6 relative to each other, and will neglect the different values of keywords FILENAME and FILTNAM1 (or their very existence). fitsdiff command-line arguments can also be set using the environment variable FITSDIFF_SETTINGS. If the FITSDIFF_SETTINGS environment variable is present, each argument present will override the corresponding argument on the command-line unless the --exact option is specified. The FITSDIFF_SETTINGS environment variable exists to make it easier to change the behavior of fitsdiff on a global level, such as in a set of regression tests. t HelpFormattercBseZd„ZRS(cCsdjt||jƒƒS(Ns {} (tformatRtwidth(tselftepilog((s?lib/python2.7/site-packages/astropy/io/fits/scripts/fitsdiff.pyt format_epilogAs(t__name__t __module__R (((s?lib/python2.7/site-packages/astropy/io/fits/scripts/fitsdiff.pyR@scCsçd„}tjdtdtdtƒƒ}|jddddd d ƒ|jd d d dddddddd dƒ|jddd dddddddd dƒ|jdddd dddddddd d ƒ|jd!d"d#d ddddd$ddd d%ƒ|jd&d'dd(dd)dtd d*ƒ|jd+dd(dd,dtd d-ƒ|jd.dddd/dtd d0ƒ|jd1d2dd3d d4ƒtj |d5ƒ}|jd6d7dd8d8|d9d:d d;dgdd<dd=d d>ƒ|jd?d@dd8d8|d9d:d d;dgddAdd=d dBƒ|j |ƒtj |dCƒ}|jdDdEdd8d8|d9d:d d;dgddFddGd dHƒ|j |ƒ|j |ƒ\}}t |ƒdIkrÝ|j dJtjdK|jjƒƒn||fS(LNcSs!t|j|jgƒ|rå|ddkrå|d}tjj|ƒsetjdj||ƒƒdSyHgt |dƒj ƒD]}|j ƒ^q~}t|j|j|ƒWqt k rá}tjdj|||ƒƒ~qXn8t|j|jg|j dƒD]}|j ƒ^qƒdS(Nit@is{} argument {} does not existtrs4reading {} for {} failed: {}; ignoring this argumentt,(tsetattrtvaluestdesttostpathtexiststlogtwarningRtopent readlineststriptIOErrortsplit(toptiontopttvaluetparsertvRtexc((s?lib/python2.7/site-packages/astropy/io/fits/scripts/fitsdiff.pyt store_listGs .  tusageR t formatters-qs--quiettactiont store_truethelps0Produce no output and just return a status code.s-ns --num-diffsttypetinttdefaulti RtnumdiffstmetavartINTEGERsiMax number of data differences (image pixel or table element) to report per extension (default %default).s-ds--difference-tolerancetfloatt tolerancetNUMBERsqDEPRECATED.
