Old versions of HOU-IP will run under Win3.1 on a 486 or better or a Macintosh II series or better. The software is provided to all teachers that go to the HOU professional development workshops and may be used on all computers used in their HOU classes. For data analysis, counts are displayed for each pixel and slice plots and histograms show brightness distributions.
Photometry routines calculate full width half max and sky-subtracted brightness.
