This page contains astronomy-related programs I've written over the years, mostly within the Interactive Reduction and Analysis Facility (IRAF) package.

PHIIRS -- Pat Hall's Infrared Imaging Reduction Software

This is a suite of IRAF tasks for the reduction of infrared imaging data. It was spawned from original tasks by Doug Williams & Anne Turner and including many cannibalized parts from the DIMSUM package of Eisenhardt et al. which, like PHIIRS, is also available from the IRAF contributed software web site.

PHAT -- Pat Hall's Add-on Tasks

PHIST -- Pat Hall's Interactive Sloan Tasks

PHUC -- Pat Hall's Utility Compilation

PHXS -- Pat Hall's X-ray Software
