The following fields are available in VOTable output.
blue: all other galaxies (SExtractor CLASS_STAR < 0.95). red: galaxies with high-confidence photo-z estimates:. yellow: stellar sources (SExtractor CLASS_STAR >=0.95). green: areas excluded from scientific analysis by our MASK key. It allows a quick-look at field-layoutĪnd object positions. Low resolution JPG image showing object positions and object masks Suitable for high-quality poster print-outs. These images allow a quick look at the data but they are probably not Low resolution true colour i', r' and g' JPG image of the CARS field. red: masks from our asteroid track analysis. magenta: masks around extended haloes of bright stars. green: stars identified in the GSC1 and GSC2 cataogues. It supports communication with all of ds9's XPA access points. The pyds9 module uses a Python interface to XPA to communicate with ds9. yellow: masks from our object density analysis and stars identified The XPA messaging system provides seamless communication between many kinds of Unix programs, including Tcl/Tk programs such as ds9. The colour coding in these files is as follows: We offer this file so that interested users can construct own masksĬontaining only parts of our global MASK key. Masking procedures are encoded with different colours (look atĮxpressions such as '# color=yellow' at the end of each line). They represent the CARS image masks described (typical gzipped file size per field: 20MB) W1m0p1_izrgu.V1.7A.Īn ASCII ds9 region file containing saoimage/ds9 polygon entries Of the most important catalogue quantities. Work on big FITS binary tables! (typical file size per field: 0.5GB!) W1m0p1_izrgu.V1.7A. An ASCII version of W1m0p1_izrgu.V1.7A.final.cat containing a subset The individual files we offer are: W1m0p1_izrgu.V1.7A.final.cat object catalogue in FITS binary format beware that they are veryīig and cumbersome to handle if you do not have efficient tools to The object detection filter (here 'i' see also 2009A&A.493.1197E) izrgu - filters involved in the product (here i', r', z', g', u*) įor catalogues etc. W1m0p1 - name of CARS field under consideration. (we discuss them on the example of the CARS pointing W1m0p1) a typical file CARS pointing we currently offer the following products Additional funding was provided by the JWST Mission office at Space Telescope Science Institute to improve capabilities for 3-D data visualization.For each 1 sq.

SAOImageDS9 development has been made possible by funding from the Chandra X-ray Science Center (CXC) and the High Energy Astrophysics Science Archive Center (HEASARC). GUI elements such as the coordinate display, panner, magnifier, horizontal and vertical graphs, button bar, and color bar can be configured via menus or the command line. All versions and platforms support a consistent set of GUI and functional capabilities.ĭS9 supports advanced features such as 2-D, 3-D and RGB frame buffers, mosaic images, tiling, blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom, cropping, rotation, pan, and a variety of coordinate systems. It requires no installation or support files. It provides for easy communication with external analysis tasks and is highly configurable and extensible via XPA and SAMP.ĭS9 is a stand-alone application. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. SAOImageDS9 is an astronomical imaging and data visualization application.
