[Clas12_calcom] [EXTERNAL] Re: RG-K latest pass0 - please take a look

[Raffaella De Vita]

Dear Annalisa,

We have checked both FT calorimeter and hodoscope and the timelines show they are in specs. 

The only note is that the FTCal pi0 timelines are more scattered than other run groups because of the lower RG-K energy.

Best regards,
	Raffaella & Nick
