[gate-users] Arbitrary Beta Spectrum

[Eric Vandervoort]

Hi Richard,
Thanks for the rapid response. Changing the histname to energy solved some
of the problems. There are still a couple of apparent typos in in the
User Manual:
1. gps should not appear in /gate/source/NAME/gps/setForcedUnstableFlag
or in /gate/source/NAME/gps/setForcedHalfLife
2. /gate/source/NAME/gps/hispoint should read histpoint.
However, I can't seem to get the /gate/source/NAME/gps/arbint Lin command
to work or (Spline etc.). According to what I can make out in
GateGeneralParticleSourceMessenger.cc this is the correct syntax but I
get a segmentation violation and the cascade of errors shown below. If I
leave the comand out the positron energies are not generated properly.
Thanks Again,
Eric
