8/2/2023 0 Comments Saoimage ds9 howto![]() ![]() It is highly configurable and extensible to meet the evolving needs of the astronomical community.ĭS9 supports advanced features such as multiple frame buffers, mosaic images, tiling, blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom, rotation, pan, and a variety of coordinate systems (including Image, Physical, Detector, and WCS). DS9 supports the direct display of FITS images and binary tables, multiple frame buffers, region cursor manipulation, many scale algorithms and colormaps, and easy communication with external analysis tasks. It also incorporates the new X Public Access ( XPA) mechanism to allow external processes to access and control its data, GUI functions, and algorithms. As of this writing v7.2 is the most up to dateversion, if a new version exists please replace the corresponding values. It is a Tk/Tcl application which utilizes the TkSAO widget set. Quite probably there is a more elegant solution, but this works.Reference Manual SAOImageDS9 Reference ManualĭS9 is the next version of the popular SAOtng display program. ![]() C 54 7 Tests Public Scripts and Test data for SAOImageDS9 Shell 2 1 Repositories SAOImageDS9 Public SAOImage DS9 is an astronomical imaging and data visualization application. Use you favourite editor to attach these lists to each other. SAOImage DS9 is an astronomical imaging and data visualization application. This will then give you a list of the RA, Dec of the same sources. If you want to match this up with the 2MASS sources then you have to "list regions" again, but this time select "fk5" as the coordinate system. SAOImage DS9, a Tcl/Tk program that uses the SAOTk widget set, is an astronomical imaging and data visualization application. If you change your window size to be what you want to crop, this will do the cropping (if zoom1). It supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. This writes the displayed image as a new FITS file, complete with any cropping and zooming included in the WCS. This will give you a list of x,y coordinates. SAOImage DS9 is an astronomical imaging and data visualization application. From this, select "x,y" for the format and "image" for the coordinate system. SAOImageDS9 Users Manual The DS9 Users Manual leads the user step-by-step through many features of ds9, such as data binning and contours. Another dialogue box will open asking you to select the format and coordinate system. MacUpdate stores previous versions of SAOImage DS9 for you since v. Then, in the main image window open the "Regions" dialogue and select "List regions". Download Old Versions of SAOImage DS9: 8.0.1 - 8.0.1 - 8.0.1 - 6.1.2 - 6.1.2 - 6.1.2 If you experience any compatibility issues with SAOImage DS9 for Mac, consider downloading one of the older versions of SAOImage DS9. From the "File" dialogue, select "Copy to regions". When you load the catalog you should see a window open entitled "2MASS Point sources" which lists all the sources in your image. Is what you are asking - how do I get the x,y coordinates of these 2MASS sources in my image? Or do you wish to know what the x,y coordinates of the actual sources in your image? If the latter then you will need some other software like Sextractor or DAOphot to do source-searching and parameterisation in your image. When you load the 2MASS catalogue, SAOimage is able to use the RA and Dec in the catalogue to calculate the x,y positions of the catalog sources in your image (and marks them as green circles). OK, it seems to me that what you have is a fits image (from where?) that has some world coordinate system information attached. ![]()
