Create a text file called temp.dat delimited with tabs where the channel number is in the first column, the photon energy in the second, and the sigma from the gaussian fit is in the third column

Then do

.L LinFit.C
MyLinFit(0,2)

E_gamma = 0.119322 +- 0.41761 + (0.937227 +- 0.000752989 keV/chan) *Chan#

Using the ROOT ntuple

MPA->Draw("0.119322+0.937227*evt.Chan>> SeRun_008(8000,0.5,8000.5)");
