This SNAPIN section reads the power and energy of each beam source and time-averages them over the interval You can also model a different beam mix from the one in the actual shot, e.g., you can specify tritium rather than deuterium beams.

\* Options are:
 1) 1A [ 96.11 +/- 1.5%,  2.36 +/- 1.5%] T 2  -1.74  V(keV) P(MW) On a# Rtan
 2) 1B [ 99.66 +/- 1.9%,  2.52 +/- 1.8%] T 2  -2.00
 3) 1C [ 97.75 +/- 1.5%,  2.53 +/- 1.5%] T 2  -2.23
 4) 2A [ 97.73 +/- 1.6%,  2.52 +/- 1.6%] T 2  -1.74
 5) 2B [ 96.16 +/- 1.6%,  2.35 +/- 1.6%] T 2  -1.99
 6) 2C [ 91.78 +/- 1.7%,  2.02 +/- 1.7%] T 2  -2.23
 7) 4A [  0.00 +/- 0.0%,  0.00 +/- 0.0%] F 2   2.29
 8) 4B [ 90.05 +/- 1.5%,  1.94 +/- 1.5%] T 2   2.05
 9) 4C [ 91.76 +/- 1.4%,  2.09 +/- 1.4%] T 2   1.80
10) 5A [ 93.94 +/- 1.7%,  2.23 +/- 1.7%] T 2   2.23
11) 5B [ 88.20 +/- 1.5%,  2.08 +/- 1.5%] T 2   1.99
12) 5C [ 96.35 +/- 1.4%,  2.34 +/- 1.4%] T 2   1.73

13) No   No beams
14) Hy   Hydrogen beams
15) De   Deuterium beams
16) Tr   Tritium beams
17) Mixed Species

18) READ beam data, source is WAVEFORMS

19) Shape and fractions
20) Thermal T conc = Beam conc   <F>
You can also specify the beam shape and energy fractions--setting these numbers will change these values for all the beams.
<1=B;> Beam option?  Sum=24.98  NB-BP-SL=0.00+/-0.0% MW <1A>: sh

<2=SF;> Set shape and fractions?   Current  Standard <H>:
\* Options are:
 1) HS Horizontal beam sigma   (m)   0.068     0.068
 2) VS Vertical   beam sigma   (m)   0.215     0.215
 3) BW Beam half-width  cutoff (m)   0.250     0.250
 4) BH Beam half-height cutoff (m)   0.520     0.520
 5) Reset beam dimensions to standard values
 6) Full, half, third energy fractions 0.46,0.28,0.25

A large collection of SNAP analysis used values for the beam footprint that are now considered to be too narrow; SNAPIN will warn you if you are not using the new standard values.
