Once the above commands have completed successfully, you can launch the interactive DS9 program by entering ds9 on the command line.Ī graphical installer is available for most platforms (Linux, Mac, Windows). Respond affirmative unless you see a good reason not to. Also, for each command, you will be prompted with the question 'Do you want to continue? '.

#Saoimage ds9 download password#

Enter your password ( not the root password!) when asked. The 'sudo' command takes care of this assuming that the corresponding privileges are enabled for your account. These commands require root access to modify files in the system directories.

On Linux distributions such as Ubuntu, DS9 can be installed via the command line as follows: $ sudo apt-get update

The following sections describe how to install one such viewer, called SAOImage DS9, or DS9 for short. While this is all very helpfull, it is often convenient to also have a dedicated FITS viewer available for interactive inspection of FITS files produced by SKIRT. Once in memory, these data can be further processed at will.īased on these packages, the Python toolkit for SKIRT or PTS offers functions to read SKIRT output files with some extra intelligence (e.g., interpreting units), and it offers high-level commands to rapidly visualize some specific SKIRT output. The almost standard Python package numpy supports reading text column files into numpy arrays, and the well-known astronomy Python package astropy supports reading FITS data into numpy arrays. The Python language ecosystem has extensive support for both data formats.

Image frames or 3D data cubes in the FITS file format, which is frequently used in astronomy because each pixel can be represented by a floating point value, allowing for a large dynamic range.

Tabular data as ASCII text column files, which can easily be processed by many software tools.

A major plus are the following: the tool is free of cost, has rich documentation for understanding where to start learning, and is supported by the astronomical community (which is prolific for quality and assistance).With few exceptions, SKIRT produces data (mock observables and diagnostic information) in two formats: To summarize, SAOImageDS9 is an excellent choice for anyone interested in conducting in-depth analysis in the astronomical field. Last but not least, with the help of the built-in Prism feature, you can preview and analyze FITS file structures, examine all the extensions (including the headers and the table data), and generate 2D and histogram plots, straight from your column data. Plus, with the new footprint server, users get increased compatibility with Chandra and Hubble Legacy Archive. This overlay displays valuable configuration options and choices for filtering, sorting, and registering unique observations (from the catalog dialog's config options). For example, when it comes to GUI changes, users can replace the light theme with the dark one, and they also have available controllers for the display of all windows, plots, and dialogs.įurthermore, the app adds an overlay onto any loaded image. SAOImageDS9 is a powerful utility that offers accessibility, solid performance, and flexible design configuration. A utility with embedded footprint server, plot dialogs support, and a Prism feature The tool enables frame adjustment on the map, different zooming in and out (with predefined levels), scale configuration, region focus and selection, or mask, graph, and crosshair parameter adjustments. The tool also allows importing arrays, n-dimensional raster data (NRRD), flat-binary raster files (ENVI), and other types of visual elements in the following formats: GIF, TIFF, JPEG, and PNG.Īfter uploading your content, you have the general viewing panel, plus two smaller windows that allow visualizing the space orientation on the map, respectively, the frame, pixel-like objects (for in-detail lookup). With SAOImageDS9 you can easily open new FITS files and start examining the content within minutes. SAOImageDS9 is a multi-platform tool, a Tk/Tcl program that enables visualizing astronomical images and analyzing complex FITS data.
