We have collected data for several values of VFS

We now fit to Landau distribution shapes:

These two figures show how well the Landau shape reproduces the pulses. The shape we used before fails to reproduce the raising side of the pulse too often.

run14062107    VFS=60

run14062108     VFS=90

This is indicating that the signal started to be corrupted. The VFS=90 does not produce good pedestals I need to redo this and VFS=120 values.

The last point on ths graph need confirmation with a run with shifted pedestals to avoid "saturated pedestal"
