FUNCTION: omni2d PURPOSE: Produces an energy or angle averaged data structure Summing is over pitch angle or energy, default is pitch angle summing. This structure can be plotted with spec2d or pitch2d. KEYWORDS: ANGLE: intarr(n) n=1 nearest angle to be summed n=2 angle range to be summed n>2 angle list to be summed ARANGE: intarr(2) angle bin range to be summed BINS - bytarr(dat.nbins) angle bins to be summed ENERGY: fltarr(2) energy range to be summed ERANGE: intarr(2) energy bin range to be summed EBINS: bytarr(dat.nenergy) energy bins to be summed NOTE: If no keyword is set, then sum over all angle to form energy spectrum CREATED BY: J.McFadden LAST MODIFICATION: 97-3-3 MOD HISTORY 97/03/03 ANGLE,ARANGE,ENERGY,ERANGE,EBINS keywords added
