This software is all written in very portable C, so it shouldĬompile and run on any computer with a C compiler.
imh, to relate image pixels to skyĬoordinates. WCSTools is a package of programs and a library of utility subroutines for settingĪnd using the world coordinate systems (WCS) in the headers of the most common astronomical image formats, FITS and IRAF. Utilities provide high-level support for processing astronomical data. Tables, as well as to raw array and binary event lists. Theįuntools library provides simplified access to FITS images and binary Programs by executing XPA client commands in the shell or by utilizingįuntools, is a "minimal buy-in" FITS library and utility package. ItĪlso provides an easy way for users to communicate with XPA-enabled Kinds of Unix programs, including X programs and Tcl/Tk programs. The XPA messaging system provides seamless communication between many Many of the routines are completely generalĪnd adaptable to other aspects of astronomical data analysis Of high-resolution UV-X-ray spectra, with emphasis on line identification,įlux measurement, and reconstruction of plasma emission measureĭistributions. Package for the Interactive Analysis of Line Emission (PINTofALE)Ī suite of IDL procedures designed to simplify the analysis
Some of theseĪre already publicly released, and some are in testing stage prior to University's Statistics department has produced a number of programsĭesigned to analyze X-ray data in the low-counts regime. The AstroStatistics collaboration between CXC and the Harvard Itself useful for the analysis of data from other X-ray and Instrument tools, CIAO is mission independent by design and has proven Observations) is the name for the suite of tools and applicationsĭeveloped at the Chandra X-Ray Center (CXC) for the analysis of dataįrom the Chandra X-Ray Observatory and other missions. Yaxx is an Open source tool to facilitate automated processing andĪnalysis of X-ray data, including spectral extraction, fitting, and It provides for easy communication with external analysis tasks and is highly configurable and extensible. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. SAOImage DS9 is an astronomical imaging and data visualization application. Harvard University Department of Astronomy.Syntax:Ĭontrols contours in the current frame. A valid contrast value is from 0 to 10 and bias value from 0 to 1. Syntax:Ĭontrols the colormap for the current frame. $ds9 -catalog symbol 2 shape "boxcircle point" $ds9 -catalog symbol condition '\$Jmag>15' $ds9 -catalog match # last two catalogs loaded condition|shape|color|text|font|fontsize|fontweight|fontslant ] All other commands operated on the last search created, unless indicated otherwise. The first three commands will create a new catalog search. Syntax:įor RGB frames, sets the current color channel to blue. Syntax:Ĭontrols binning factor, binning buffer size, and binning function for binning FITS bin tables. Select ASINH scale function for the current frame. $ds9 -analysis 0 # invoke first analysis task Can also be used to display a message and display text in the text dialog window. Tasks are numbered as they are loaded, starting with 0. Syntax:Ĭontrols the World Coordinate System alignment for the current frame. Next, bar.fits is loaded and the colormap for bar.fits is changed to I8. Then the colormap for foo.fits is changed to Heat and the scale changed to zscale. For example, the following command line option is used: $ds9 -tile foo.fits -cmap Heat -zscale bar.fits -cmap I8įirst DS9 is put in tile mode, then foo.fits is loaded. Therefore, it is possible to use command line options as a little script. Command Line Options Command Line OptionsĭS9 will process each command line option, one at a time, as the last step in the initialization process.
