FUNCTION: n_2d_new(dat,ENERGY=en,ERANGE=er,EBINS=ebins,ANGLE=an,ARANGE=ar,BINS=bins) INPUT: dat: structure, 2d data structure filled by get_eesa_surv, get_eesa_burst, etc. KEYWORDS ENERGY: fltarr(2), optional, min,max energy range for integration ERANGE: fltarr(2), optional, min,max energy bin numbers for integration EBINS: bytarr(na), optional, energy bins array for integration 0,1=exclude,include, na = dat.nenergy ANGLE: fltarr(2), optional, min,max pitch angle range for integration ARANGE: fltarr(2), optional, min,max angle bin numbers for integration BINS: bytarr(nb), optional, angle bins array for integration 0,1=exclude,include, nb = dat.ntheta BINS: bytarr(na,nb), optional, energy/angle bins array for integration 0,1=exclude,include PURPOSE: Returns the density, n, 1/cm^3, corrects for spacecraft potential if dat.sc_pot exists NOTES: Function normally called by "get_2dt.pro" to generate time series data for "tplot.pro".
