[Clas12_verystrange] Additional background lund files

[Michael Dugger]

Hi,

A request was made for me to provide additional background lund files.

I have Pythia generated background event files in lund format at

/lustre/expphy/volatile/clas12/dugger/vsGen/background

There are 200 individual files.

The files background_1.lund to background_100.lund are the original
100 files that I had made previously (each file contains 10,000 events).

The files background_101.lund to background_200.lund are new and have
ten times the events per file than the original set. These have 100,000
events per file.

The grand total is 11 million events.

Some generation details:

* Virtual photon energy from 5 to 10.5 GeV

* Primary vertex covers target of length 5 cm

* Target centered at (0,0,0)

Take care,
Michael
