The software distribution was updated 2/8/13. The major change was an increase in the number of components in Props.xlsx and props.m. Also, a gammafitTxy.m routine was added.
The programs are provided in a single windows .zip file. It is recommended that you remove them from the zip file before using them. The zip file can be maintained as a backup. In Windows, open the archive with Windows Explorer, and then drag or copy/paste them into the folder of your choice. If your computer has another zip utility installed that you are not comfortable using, after saving the file to your computer, you can probably find the Windows Explorer by right-clicking on the zip file and using 'Open With...'.
The software is distributed on the 'chethermo' account on sourceforge.net, click here.
