Improvements to handling FITS files with NULL values (ie BLANK keyword), especially when combined with scaled integer images (BSCALE/BZERO).ĭmdiff has been through a major overhaul to provide more robust comparison, especially with arrays and world coordinate system (WCS) parameters.Ī new adaptive binning tool, dmradar, implements a polar version of the quad-tree algorithm.ĬIAO contributed script updates since the previous CIAO release include: įix to dmextract to properly use the first good time interval (GTI) when computing exposures for lightcurve bins. įix for the vignetting component of the effective area as computed by mkarf, mkgarf, and mkinstmap. This affects mkarf, mkgarf, mkwarf, and mkinstmap. There are several important tool bug fixes includingįix for the missing frame store shadow badpixel when creating ARFs and exposure maps. Most of the prism functionality can now be found in ds9 using the File → Prism option. The prism application has been removed from CIAO.

Notable change and improvements (read the complete release notes for full details):ĬIAO can be installed using the conda package manager. DS9 can also be downloaded and installed as a stand-alone application from. ĬIAO 4.14 includes version 8.3 of SAOImage DS9 (the astronomical imaging and data visualization application).

SAOImage DS9 is a completely independent application (no need to install third-party utilities and libraries), developed at the Smithsonian astrophysical Observatory (CAO) with funding from the research center Chandra X-ray Science Center (CXC) and the High Energy Astrophysics Science Archive Center (HEASARC). The management of the application (set of applications) is performed using the mouse and/or keyboard combinations. SAOImage DS9 can export the result into a color image with logarithmic, linear, quadratic, square and power-the color distribution, as well as a separate channel (RGB/Red, Green, Blue) in the FITS file-compatible format (*.fits *.fit *.fts *.fits.gz *.fits.bz2 *.fits.Z *.fits.z), if necessary, further image processing can be done in any graphics editor (supports FITS format, such as GIMP). SAOImage DS9 allows with standard astronomical image manipulation (rotate, crop, resize, and more), supports panning, 2D and 3D representation of astronomical data, can be expanded with plugins and scripts, as well as be used as a module in other applications (such as application package IRAF). It is possible to access local data and files from the network, supports work with multiple files, as presented in several ways (mosaics, tiles, etc).

SAOImage DS9 supports astronomical images and binary tables, providing data analysis methods allowing to cope with all the challenges that astronomers tasks. SAOImage DS9 includes more than twenty specialized tools for analysis and processing of astronomical data from optical and infrared telescopes, you can work with any astronomical data in FITS format / FIT (*.fits, *.fit, *.FTS, *.fts, *.DS, *.ds), including compressed (*.fits.gz *.fits.bz2 *.fits.Z *.fits.z *.fitz *.FITZ *.ftz *.FTZ *.fz *.FZ).įITS ( Flexible Image Transport System) is a digital file format used in science for the storage, transfer and editing metadata (spreadsheet), most often this format is used in astronomy. SAOImage DS9 is an intuitive and configurable user interface, parameters can be set from the command line or from the menu interface are activated only work-tools (display coordinates, horizontal and vertical graphs, dashboard, start button tools, magnifier, etc.).
