[Clas12_calcom] New data sample

[Raffaella De Vita]

Dear All,
we have produced a new sample of data using the latest gemc (4a.2.0) and reconstruction (4a.7.2) after all the fixes. Files are in /volatile/clas12/devita/challenge/sample-4a.7.2
Again, I would like to ask all detector groups to take a look, possibly run their calibration suites on these files and give us feedback.
Best regards,
   Raffaella
