The
format of the offsets "d[variablename]" are the same as those in
"heepcheck.f". For example, for the electron in the sos
p_e = ssp*(1-dp_ss/1000.0)
th_e [rad] =
mysstheta-dth_ss/1000.0
p_p =
hsp*(1-dp_hs/1000.0)
th_p [rad]=
myhstheta-dth_hs/1000.0
newE=e_beam*(1+dE/1000.0)
newssxptar= ssxptar- dssxptar
The
plots showing the results after the offsets, and the radiation
offsets are here.
SOS momentum saturation curve
Red data points are Tanja's results, and the dot-dashed curve is their
parameterization -0.36-0.0632*exp(x**3.004)
Black data points are from the 2004 running period and the solid curve
is the parameterization -0.3844-0.01778*exp(x**3.3971)
