Difference between Delphes3 and Delphes2 cards

Description

Hello,

It seems we observe a difference between Delphes3 and Delphes2 cards for the S term of forward
ECAL:

Delphes2 DetectorCard_ATLAS.dat: ELG_Sfwd 0.285 S term for forward FCAL

while in Delphes3 (delphes_card_ATLAS.tcl) the constant term is x10 larger:
(see ECalResolutionFormula and the number energy*2.0852)

which one is correct? We cannot access http://villaolmo.mib.infn.it/ICATPP9th_2005/Calorimetry/Schram.p.pdf to check this number,

Related to this, do you expect any another difference between Delphes2 and Delphes3 cards?

best, Sergei

The typo in the S term of the forward ECAL is fixed.

Here is a paper with the numbers for the forward calorimeter resolution:
