[Halld-offline] generation of secondaries in hdgeant

[Kei Moriya]

Hi,

For my "bug" of finding only ~40% of my Xi- going to
Lambda's, it turns out I had the DCAY flag set to 0
in the control.in file for hdgeant. With the flag set to
DCAY 1 (default), I get 50 Lambda's generated for 50 Xi- events.

Does anybody know why ~40% of my events have Lambda's
when the flag is set to 0? Is this the expected behavior?

According to the file
$HALLD_HOME/src/programs/Simulation/HDGeant/control.in,
c DCAY 0 no decay in flight
c      1 decay in flight with generation of secondaries (default)
c      2 decay in flight without generation of secondaries
