FV FITS View install

less than 1 minute read

Ubuntu 18.04 repo ftools-fv provides NASA FV FITS viewer. FV is a highly useful program to view FITS tables and images. The FITS format is an old but frequently used format in astronomical imagery. However, the Ubuntu 18.04 repo version of FV still is broken as of summer 2018.

Workaround:

  1. download the Linux FV binaries from NASA and extract to home directory.
  2. remove the broken Ubuntu 18.04 FV
    apt remove ftools-fv
    
  3. point to the new FV by editing ~/.bash_aliases:
    export fv=~/fv5.5/fv
    

Notes

The error I still get with Ubuntu 18.04 repo of ftools-fv is:

Error in startup script: can’t find package Itk while executing “package require Itk” (procedure “fvInit” line 11) invoked from within “fvInit” (“eval” body line 1) invoked from within “eval fvInit $argv” (file “/usr/share/ftools/fv/fvInit.tcl” line 15)
