Bug Description
Hi Paolo,
When running on a (read-only) system based on Ubuntu,
the HW6 shower crash with:
At line 134 of file ../srcHerwig/
Fortran runtime error: Bad real number in item 6 of list input
The associated line are written below:
WRITE(
READ(
WRITE(
READ(
Now if I look at what I guess is the input file (end of this email the full file):
125.0 0.006382339 ! M_H, Ga_H
0.32 0.32 0.5 1.55 0.75 ! quark and gluon masses
It sounds clear that one entry is missing in that line.
Is this a 4/5 flavour issue?
I'm running now on my laptop to test ( p p > t t~ [QCD]) but I guess that even if I do not have a crash this problem might still be present.
What is your opinion on this? (and how do you think that we have to solve that issue)
Cheers,
Olivier

Just to report my result on my mac:
the file is like this:
125.0 0.006382339 ! M_H, Ga_H
0.32 0.32 0.5 1.55 4.95 0.75 ! quark and gluon masses
So in this case no issue at ALL (good, I was worried that it was returning something stupid)
