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 = mysstheta-dth_ss/1000.0   [rad]
         p_p = hsp*(1-dp_hs/1000.0)
         th_p = myhstheta-dth_hs/1000.0   [rad]
         newE=e_beam*(1+dE/1000.0)
         newssxptar= ssxptar- dssxptar

For the electron in the HMS,  change p_e-> p_p and th_e-> th_p, and vice-versa.  The other two transformations remain the same.

The plots showing the results after the offsets, and the radiation offsets are here.


Tanja's results for the SOS saturation can be found here, and are listed below.

SOS momentum saturation curve

Red data points are Tanja's results, and the 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 line is the parameterization  -0.998-0.0136*EXP(x**3.4422)



SOS ssxptar offset  (dssxptar vs. P_sos)

The solid line is the parameterization -0.001542-0.004818*x
