Re: hac-tile energy resolution

Dear Alfredo and Dear Fluka Experts

In my previous mail I have sent hadronic calorimeter related problem.
As Alfredo said we have removed PHYSICS cards (and also LOW-BIAS has removed).
Could you find both my input and my myrfluka.C root files as an attachment
of this mail.
The obtained energy resolution (SigmaE_{rms}/E_{mean})
is equal to 0.2449 which is 2.57 times higher than geant-4 results.

Could you please tell me is there any wrong in my input (or myrfluka)

Thanks in advance,
Best Regards
Ertan
