PMTI is a set of unix/bsd/linux programs for automated photometry and 
data reduction by Dominic-Luc Webb. This package includes PMTI, which 
automates background subtraction of PMT and CCD recordings using 
background values saved in the first columns of data files. There is 
also AUC, which can take the PMTI corrected values and seek out 
deflections from a baseline (calculated from a linear regression line) 
and calculates area under curve(s). This is a pre-alpha release but all 
code works as intended and compiles with gcc with no warnings or errors. 
The primary download site is iraf.noao.edu/contrib.
