[g13] example rootfile from my previous pi-p analysis

[Daria Sokhan]

Hi everyone,

Following today's discussion here's a link to a root output file from
my previous analysis run. The following things have been added to the
ntuples for the next analysis:

http://www.jlab.org/~daria/1500_4065_1700_I.root

* event ID (from HEAD bank)
* position of coherent edge for each event
* Tagger E-channel id for the photon in each event

I think that's all I've added so far. There's been some tidying of
cuts, etc, but no more changes to the histograms / ntuples.

Please feel free to make suggestions on what else would be useful to
include for monitoring -- either to the ntuples if event-by-event data
is needed, or any more histograms! And let me know if it's not clear
what something is. The event ntuples (AMO, PARA, PERP) in the root
file contain the following:

Lab photon energy,
invariant mass of reaction in CM,
Cos(theta) of pi- in CM,
phi angle (of polarisation vector wrt y-axis) in CM,
missing momentum,
Cos(theta) of pi- in lab,
phi of pi- in lab

The two stats ntuples have the numbers of particles remaining after
every single cut.

Cheers,
Daria
