Updated .FITS file loading

This project provides updates to the native "Load FITS" package in IGOR. The .FITS (Flexible Image Transport System) file format is for storage, transmission, and processing of scientific and other images. There is much more information on the web, and is supported by NASA Goddard Space Flight Center at http://fits.gsfc.nasa.gov/ .

As of Igor version 6.12, FITS files can be read natively via Data > Load Waves > Packages > Load FITS. This package provides updates to that native routine.


  • Read files with multiple HDUs into IGOR as waves
  • Minor tweaks to original loading routines

Planned Features (open for collaboration):

  • writing .FITS files

  • ability to read just headers from files

  • ability to write headers to files

  • Implementation:

    • Download the file to your Igor Pro User Procedures folder.

    • In Igor, add the following to the main Procedure window: #include "FITS Loader Multi"

    • On the command line, issue: CreateFitsLoader()

    • Use the GUI to load/unload FITS files
