It less than optimal for sparse high energy data. The contour algorithm currently implemented is a general purposeĪlgorithm, good for most images. Printing of image/contours also is supported. It provides for easy communication with external analysis tasks. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. When you paste a contour, you choose which coordinate system SAOImage DS9 is an astronomical imaging and data visualization application. You can generate contours for each frame and cut/paste them into fixed some minor problems with Mosaic ImagesĮxample: $ ds9 snr.fits # assume 'X' or 'x' and 'Y' or 'y' column $ ds9 snr.fits $ ds9 snr.fits # assumes EVENTS or STDEVT extension $ ds9 snr.fits # bin on RAWX/RAWY column.Note: this does not include space needed for menus.Įxample: $ ds9 $ ds9 geometry command line option: $ ds9 -geometry 600x500.fixed bug with zscale and minmax preferences.# default name of 'DS9' $ ds9 -title foo& # name of 'foo' $ xpaset -p foo colormap BB # change colormap for 'foo' $ xpaset -p :foo colormap A # change colormap for 'foo' $ xpaset -p DS9:foo colormap BB # change colormap for 'foo' $ xpaset -p DS9: colormap I8 # change colormap for 'DS9 & foo' If you are still using an IDL 7.x version, you can still use the older 2.3 version.
XPA Note: xpa class and name for ds9 - xpa class : 'DS9' - xpa name : 'DS9' both class and name are case sensitive To specify a different xpa name for this application use the -title command line option: $ ds9& It looks a lot like SAOimage or DS9, so if youre used to using those. Fixes a rather nasty bug with coordinates.Įxample: $ ds9& $ xpaget DS9 # will list all public access points $ xpaset -p DS9 colormap BB # change colormap $ xpaset -p DS9 file snr.fits # load a fits file $ cat snr.fits | xpaset DS9 fits # load via XPA $ cat snr.fits | xpaset DS9 fits foo # load via.
