[Clas12_verystrange] Banks, trigger bits and Link to presentation

[Shankar Adhikari]

Hi Mike,

I have a filtered file which only have those banks you asked for along with
"RUN::config" , "Run::rf" and "RUN::trigger".
Please look at the location below. It includes all the files of run number
3050 that are located in /volatile/clas12/data/rg-a/pass0/tag5b.3.3/.
I merged 686 files to a single file.

/w/hallb-scifs17exp/clas12/shankar/pass0/tag5b.3.3

Please let me know if you have any question.

Thank you

Shankar
