On page 10 I mention a residual problem on the fifth order fit for 25
degree bend for the 3 MeV/c point. I just checked it and P is OK. It
may be that I simply transferred too few decimal places from my
spreadsheet to my graphing package for low momenta. I should have
transferred four, not three, if I wanted high accuracy at low momentum.
Yet when I add a decimal place to that one point, the residual gets
larger, not smaller. I should probably go back and redo everything with
four decimal places for P. Argh.
OTOH, this experiment doesn't care about anything below 7.85 MeV KE and
my residuals are fine there. So maybe I won't. Anyone got a summer
student who could be persuaded to take my spreadsheets with all
available decimal places and re-fit everything in R? A valuable skill
in the job market is R.
