Subject: [Rich] [EXTERNAL] new rich monitoring histograms

Hi all,
you may have noticed that the RICH monitoring histograms have been
changed.
I defined these new histograms following the discussions we had at the
last RICH meeting and discussions with Raffaella. Then she implemented
the modifications in mon12. She also rewrote the way the geometry is
handled to make it more clear.

I apologize for not having discussed the new histograms with everyone, I
just briefly illustrated them yesterday to Marco Contalbrigo and Fatiha.
It is nothing really new, but I think it is a better way to visualize
the status of the detector.
The only real difference is that now all the plots are showing only
reconstructed hits, not edges.
And I used the running average number of counts per channel <N> to set
the color scales and draw some reference lines.

Now we have only two tabs instead of one.
One tab is showing the same hit maps as before, but with a log color
scale and with max proportional to <N>. Here one is supposed to find
problems with missing PMTs or tiles (as happened few days ago and also
yesterday).

The second tab has 4 plots.
The top left and right show the number of hits per channels and per pmt.
From the left plot, one should be able to see new hot channels (counts
significantly above the line) or new dead channels (zero counts).
From the right plot again one should see possible missing PMTs or tiles.

The two bottom plots show the leading edge time and the
time-over-threshold per PMT. From these plots one should check that the
signal is well within the DAQ time window (left) and of the expected
shape (right).
The lines are showing more or less where we expect to see the signal.

As last step to conclude this work I will write a short paragraph to be
added in the mon12 manual.

Best regards,
Marco
