pros -- Supporting documentation (help files) for the xray package
In addition to standard package and task help, which is available throughout all of IRAF, there are other types of help files available within the IRAF/XRAY package.
"Explain" help files give background information for the packages within the xray package (PROS) and contain detailed algorithm information. These are usually of the form:
help explain_<package> or phelp explain_<package>Since PROS is designed as a set of independent tools, to provide maximum flexibility and user-customization, it is often necessary to run several individual tasks to perform a complete analysis. Help with accomplishing this type of approach is usually of the form:
help using_<package> or phelp using_<package>and gives an overview of the interaction of the related tasks within the package.
"Extra" help files available in the PROS/XRAY package include:
XRAY bugs filter coords missions exposure qpoe extensions qpmerge explain_errors * rosat_files explain_xdata regions explain_screens * release_xray extensions * wcsbug file_compare xspec_interface XSPATIAL prf (or psf) XSPATIAL.DETECT explain_detect using_detect XPLOT using_xplot XTIMING.TIMCOR using_timcor utc XSPECTRAL using_spectral pspc_fitting ( * = new help file in PROS 2.4. )
Standard package or task help is invoked with the desired task-name:
help <task-name or package-name>For a package name, this will provide a menu listing all tasks within the package with one-line descriptions of their functions, e.g.,
help xray help xspectral
For a task name, detailed information about how to run specific tasks is displayed, including a description of input parameters, and examples of output, e.g.,
Often times, it is more useful to do a keyword search, to find all TASKS relevant to a particular topic. For this there are two possible methods:
references <keyword>which is an IRAF facility available on all systems and also:
xapropos <keyword>which is dependent on the CTIO/APROPOS task. PROS has built reference libraries from IRAF/NOAO/TABLES/PROS and STSDAS which will be searched.
If you have questions or need specific help unavailable in the on-line help, you can use e-mail to get support from:

Some of the format Science Specification documents are also available in TeX format, as follows:
science spec: description: ------------ ------------ xspatialdoc$spatial.<tex,dvi> specs imsmooth,immodel,vignetting, imcontour, qpotate xspatialdoc$arrayers.<tex,dvi> specs for dealing with errors (imsmooth) xtimingdoc$timing.<tex,dvi> specs for timing tasks, ltcurv,fft,etc. xspectraldoc$spectral.<tex,dvi> specs for spectral fittingNote that these files are tex (or dvi) files. You can `cd <package>doc$' and then use pstex or equivalent to make a hardcopy. Remember to cd back to your working directory afterwards.
