Unable to find cosolidated cross section file

Asked by manish sharma

Hi,
I am trying to make a scan over a parameter and plot a graph of cross-section against it. It is showing separate results(cross section values) for each iteration .
But is it possible to get a consolidated file containing the scan results (i.e. all iterations together)?

Would appreciate any help in this regard.

Thanks and regards,
Manish Sharma.

Dear Manish,
if I understand you correctly you want to do scan over a parameter and then get an ASCII file containing cross section [and maybe cross section error] for the corresponding scan points. You can take a look in the Z-lineshape.sin from share/examples, but mainly this works like:

process eemm = e1, E1 => e2, E2

plot foo

scan sqrts = (250 GeV => 500 GeV /+ 10 GeV) {
  integrate (eemm)
  record foo (sqrts, integral (eemm), error (eemm))
}

write_analysis { $out_file = "foo.dat" }

This will give you a file foo.dat with ASCII outout if bins with cross section and cross section errors.
Does this answer your question?
Cheers,
