[Hps-ecal] Data for ECal studies

[dupre]

Hello everyone,

We took some data for Coulomb scattering calibration. They are the runs 
from 3393 to 3402, please see the logbook for details of trigger and 
masks. We ran the runs 3395 and following with masks to select higher 
angles and allow higher luminosities.

We took some data to study pile-up in raw mode. They are the runs 3417 
to 3422 with a Aprime kind of trigger. These runs use 10, 50, 50, 100, 
150 and 200 nA currents respectively.

Finally we have some data for trigger studies. They are the runs from 
3423 to 3427 with loose two cluster trigger and a tighter two cluster 
trigger. We activated in the tighter trigger the energy-distance cut for 
3423, the coplanarity cut for 3424 and 3426 (3425 is junk), all A' cuts 
for 3427. The runs 3428 and 3429 have data from 1 cluster and 2 cluster 
trigger to check what two cluster trigger actually trigs.

I think that is all the specific data we need, so feel free to look at 
these to check you have all that you need! Let me know if you need other 
kinds of data, we have only 24h more of beam!
