[gate-users] Arbitrary Beta Spectrum

[evander at phas.ubc.ca]

Hello,
I was wondering if anyone had experience using the arbitrary energy-type
positron source. I encounter the following error message using the
"histname" gps command:

parameter value is not listed in the candidate List.
***** Illegal parameter (0) </gate/source/NAME/gps/histname MySource>
********** Command ignored *****

The "emin" and "emax" commands are recongnized but all subsequent commands
involving "hispoint" and the "arbint" commands give me COMMAND NOT FOUND
errors. I've just cut and paste from the users manual into my source macro
(shown below), to see if it was some trivial syntax error but I'm still
getting the same errors. Any help would be greatly appreciated.
Thanks,
Eric
