Download fv v5.3 Here

fv is built and distributed as a standard component of the large HEASOFT package of programs for manipulating and analyzing FITS data files, but you can also download the latest version of the fv binary executable by itself from this page.

Versions of fv are available for various Unix platforms (including Mac OS X), for Windows PCs, and for older versions of Mac OS. In each case the distribution is completely self-contained and includes several sample FITS files that can be used to explore fv's capabilities.

If you experience problems using the following FTP links to download this software, click here for instructions on downloading fv using 'HTTP'.

Executable Binary Distributions

Linux / Solaris
Download the tar file appropriate for your platform:

  • PC Linux
  • PC Linux (64-bit)
  • Sun Solaris

    These links will retrieve a gzipped tar file (roughly 3 MB in size). To unpack the file, type:

       > gunzip -c fv53_<ARCH>.tar.gz | tar xf -
    where <ARCH> depends on the file downloaded. This will create a fv5.3 directory containing a platform-specific directory (pre-compiled binaries and libraries used by fv), associated documentation, sample data, and sample scripts. Once unpacked, fv can be run immediately; either add the fv5.3 directory to your executable PATH environment variable, or `cd' to that directory and then type `./fv'.

    NOTE to Users with fv installed as part of the HEASOFT software package:
    If you want to replace the fv in your HEASOFT distribution with the newest version of fv, simply move (or copy) the contents of the untarred fv5.3/ directory into the $HEADAS/bin/ directory. You may want to move aside the existing $HEADAS/bin/fv to e.g. $HEADAS/bin/fv_old first since you will be copying in a new fv executable.

  • Windows PCs

    Windows users should download this self-extracting executable file (7.3Mb). Once you've downloaded the file, double-click on it to launch InstallShield, which will guide you through the installation process.

    fv installation will produce two more icons (in addition to the regular fv icon), Hera and Student Hera, on user's desktop.

    Note: During the installation process, if you un-checked the option "Create a desktop icon" under "Select Additional Tasks" panel, there will be no fv, Hera and Student Hera icons created on the desktop.

    For information to Hera and Student Hera, please visit these pages:

    For Hera, please go here

    For Student Hera please go here

    Mac OS-X

    Download Mac OS X package then drag it onto Stuffit Expander to decompress it (Stuffit Expander may launch and decompress the file automatically). If the disk image doesn't mount automatically, double-click on the .dmg file to mount it. Once the disk image mounts, open it, and drag the fv icon onto your hard disk. We recommend that you copy it to the Applications folder.

    Same as installation for Microsoft Windows, fv installation for Mac OS X, as of version 5.3 will also create 2 more icons for user to try out HEASARC Hera service. And it is also recommand that user copies them to the Applications folder to connect to Hera and Student Hera.

    To start Fv double click on the fv icon or type open -a fv from the command line. As with other Mac versions of Fv, the X11 graphical environment needs to be installed.

    Select QUIT (command-Q) from the fv menu if the Quit button on the Fv interface does not work.

    Older versions of Mac OS (before Mac OS X)

    Users of previous Mac operating systems (OS-8, OS-9) should download the older Fv 3.0 executable here (1.9 Meg). The lastest version of fv is not supported on the older Mac OS. Decompress the file and run fv. An included AppleScript can be used to set files' Creator/File types so that they will be opened by fv when double-clicked. Use the "File Exchange" control panel to have the ".fits" (and other) filename extension(s) recognized as being a fv FITS file when moving files to your computer from PCs or downloading them from the internet. More details can be found in an included README file.

    Source Code Distribution

    A source code distribution of fv 5.3 is now available here. Users should refer to the standard HEASOFT-INSTALL document for instructions on how to build HEASOFT source code distributions, specifically the section titled "STEP BY STEP INSTALLATION INSTRUCTIONS".
