I. Introduction
I.1 What they do
1. These scripts are designed to process data files obtained in the PMT surface scan
and quantum efficiency experiments. The results are presented in both numerical
and graphical form.
2. The surface scan the scripts (especially the pamunif.m script) compute the
parameters of the ideal surface as described in [1]. They also produce the intensity
plot, the radial profile plot and the azimuthal profile plots.
3. The quantum efficiency (QE) scripts display the quantum efficiency plot and they
compute the average of QE over the range 380-450 nm.
I.2 What they do not do
1. The scripts were not written to be foolproof. If one gives them a reason to crash
they will crash. (They might also crash without a reason)
2. They cannot guess the correct initial values for the optimization process.
3. They cannot detect a corrupted or incorrect data file. (or, more precisely, they will
detect it by crashing)
