;PURPOSE:
;This crib shows how to extract the ground-based moments from level 2
;ESA data files
;
;Note on variable/routine names: Particle variables/routines follow
;the naming convention th[a/b/c/d/e]_p[e/s][i/e][f/r/b] where
;th=themis, [a/b/c/d/e]=spacecraft, p=particle, [e/s]=ESA or SST
;instrument, [i/e]=ion/electron, [f/r/b]=full/reduced/burst
