![]() Quite probably there is a more elegant solution, but this works. Use you favourite editor to attach these lists to each other. This will then give you a list of the RA, Dec of the same sources. The global Milky Way Star Clusters (MWSC) survey provided new cluster membership lists and mean cluster parameters. 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. This will give you a list of x,y coordinates. Saoimage ds9 get position of star software#But it is a literal truth, too, as Linux and open source software power scores of professional and amateur astronomy projects. From this, select "x,y" for the format and "image" for the coordinate system. They are among the oldest stars found in a galaxy, and their presence and abundance in a galaxy’s halo offer insight on the age, composition, and formation of the galaxy.1 I used a Hubble Space Telescope (HST) image and SAOImage DS9, a powerful imaging tool used to analyze astronomical data, to identify the size and locate the position of. Considering Linux’s foothold in everything from embedded devices to supercomputers, describing the project’s growth as astronomical is no exaggeration. Another dialogue box will open asking you to select the format and coordinate system. Then, in the main image window open the "Regions" dialogue and select "List regions". From the "File" dialogue, select "Copy to regions". For comparison, consider getting the crosshair coordinates from ds9. When you load the catalog you should see a window open entitled "2MASS Point sources" which lists all the sources in your image. As a general rule, functions which are available in the ds9 GUI can be accessed through XPA. 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. ![]()
