[Rich] event loss due to misalignment

[Sergio Anefalos Pereira]

Dear all,

Following our last meeting discussion about event losses due to the misalignment "filter", I've looked the 
exact number of events with and without the break for all runs and also for each kind of run separately.
The overall loss due to misalignment break is 40.86%, where we have the following partial contributions:
- alignment runs 1.5031%
- direct light 15.9443%
- reflected light 23.4157%.

In the lines below "New cook" refers to the runs cooked with a break after a misalignment event is found,
and the "Old cook" to the runs without a break.

ALL RUNS
-----------
New cook = 1,876,466 events and Old cook = 3,173,089 events, resulting in 40.8631% of event loss.

ALIGNMENT
--------------
New cook = 79,259 events and Old cook = 126,955 events.

DIRECT LIGHT
---------------
New cook = 823,878 events and Old cook = 1,329,804 events.

REFLECTED LIGHT
--------------------
New cook = 973,329 events and Old cook = 1,716,330 events.

All the best,
Sergio
