Some nominal values for EMMA: 

Energy acceptance: +25% -17%
m/q acceptance: +/- 3.5%
mass dispersion in focal plane: 10 mm/%
angular acceptance: +/- 3.6 deg by +/- 3.6 deg (15 msr)

Functionality/Usage changes updates: 

Nov. 5 Update: - Energy spectrum reading is implemented. To utilise it, 
go to UserDir where the rest of the input files are located. The 
spectrum, energySpectrum.dat, is located there. Note: it is currently 
configured to ignore the energy input information (beam energy and 
energy spread) in beam.dat. The energy spectrum reading also only 
affects beam simulations, and not anything else like alphasource. 

Nov. 8 Update: - Now, you can switch between if you read energy from a 
user-defined spectrum (see above) or use the default gaussian energy that's 
already implemented in beam.dat. 
To change this option, simply change the last (9th) line in beam.dat to 
SPEC or GAUS. It is set to SPEC by default. 

Nov. 15 Update: - added a histogram as part of the output data file which
displays the energy spectrum that was emitted from the target. Useful
for verification purposes. 

Nov. 19 Update: - added a histogram in the output file that displays the 
location of beam emissions at the target plane (in terms of X and Y). 

Nov. 21 Update: - added a histogram in the output file that displays the 
x and y components of the particle direction unit vectors (Target Plane
Transverse Emission Components).
