Thanks for showing me my error.

A few more questions/observations.

I am unable to run macros unless I use the full path of PF2EvalBatch.h in the PScatterCrossSection.h

Error: cannot open file "PF2EvalBatch.h"  /Users/Mike/Pluto/pluto_v5.40.5/plugins/scatter_mod/PScatterCrossSection.h:15:



Also, I am unclear on what SetNpx/y does. Looking in the code I see that on line 58
if (npy>0) pf2->SetNpx(npy);

Is this suppose to be SetNpx for npy? Could you also elaborate more on this functionality?


Also, beam smearing is not working with the PScatterCrossSection. I checked this by smearing the beam 1.1 -> 5.7 GeV in the lab, translating this to c.m. energy and generate. The lab beam distribution is flat, instead of a bremsstrahlung (1/x) function I input into beam smear, however the c.m energy is not flat(see below). I am sure I know a work around for this, but I thought I would bring it to your attention.

Lab Frame:

index.php?t=getfile&id=7101&private=0

c.m. Frame:

index.php?t=getfile&id=7102&private=0



And lastly,

Quote:


PS: Do not forget that the y-axis (a linear increase of _f) was just dummy.


I do not understand this. Once I corrected my sytax for my double boost, I checked my distributed cos(theta) of the PLUTO generation. It looks like the input. (see below) Would you also elaborate more on on the meaning of your P.S.

Thanks
Michael

INPUT:
index.php?t=getfile&id=7100&private=0


PLUTO OUTPUT:
index.php?t=getfile&id=7099&private=0
