Hoi, I ran and set the emc energy of all truth-identified klong clusters to 0. The result is Batch Description BRBR =================================================================== o12 KL EMC clusters = 0 0.0203027 +- 0.00250567 o01 with KL scaling 0.0201532 +- 0.00251257 o00 default 0.0202685 +- 0.00250473 At least it's in the other direction compared to increasing the deposited energy with Alessio's scaling. In case you check in the logfiles (at the usual places): The printout's claim of scaling with a number is wrong, because I only updated the code but not the printout... Cheers, --U.
