Cosmic ray runs.

Hello, all.

John Ficenec and I ran several cosmic ray runs over the weekend. Only the
time of flight crate was read out and the trigger was provided by the time
of flight pretrigger boards. We ran with one sector at a time in the
trigger. I have used Maurik's counter-to-counter
filter program to process the data. The filtered files are located in
/work/clas/disk1/test/tof_cosmics and are called:

c2c_4271.evt (Sector 5)
c2c_4272.evt (Sector 1)
c2c_4273.evt (Sector 6)
c2c_4278.evt (Sector 3)*
c2c_4279.evt (Sector 4)

* Apparently there was some problem with run 4278, since comparatively
few events survived the filter. Also we were not able to run with sector 2
as the trigger for some reason, so there is no data file for sector 2.

There are also a series of rzn files in this subdirectory. I created
those with some recsis user code using the filtered files as the input.

Simon.
