Hi Michael, Eugene,
Here is a plot of my polynomials fitting those offsets:
http://einstein.unh.edu/~adrian/meeting0905/7wcCutsPhi14Pol7.gif
I think this is what Michael asked me about today over the phone (Eugene
also had a related question in an email). I showed many times these
plots before... The black curves fitting the blue points representing the
offsets are the polynomials I sent last night (of course, only the top
four plots in the above gif are related to momentum corrections).
I guess I could have used lower degree polynomials, but I just wanted to
use the same degree for all quantities shown in the gif... and 7 seems to
represent them well, without wiggling too much.
I hope this helps,
Adrian
