[Dsg-rich] RICH is taking cosmic muons data

[Patrizia Rossi]

Dear Valery,

thank you very much for sharing this good news within the Hall B collaboration.
This project which started several years ago and received the dedication, hard work and enthusiasm of many people (physicists and technicians) seems to become a reality.
This is not the end of the story, but doubtless it is a very good starting point.

Thank you very much to everybody who worked very hard, especially in these last days, to get these beautiful rings!

So in total we have 6144 RICH channels. The trigger is using information from two trigger RICH tiles and two scintillator counters. Please take a look to the attached plots.
