Equivalentsphere_data mat files contain the following arrays for spheres with the same volume as the spheroid of the given axis ratio:

  ABRATIO -- axis ratio of spheroid
  D -- equivalent sphere diameter (micron) for sphere with same volume
  Mri -- real part of index of refraction relative to water
  Mrr -- imaginary part of index of refraction relative to water
  lambda -- wavelength in water in microns
  sjCabs -- absorption cross section
  sjCbb -- backscattering cross section
  sjCext -- attenuation cross section
  sjCsca -- scattering cross section
  sjF11 -- phase function
  sjG -- cross section


Spheroid_data mat files contain the following arrays:

  ABRATIO -- axis ratio of spheroid
  D -- equivalent sphere diameter (micron) for sphere with same volume
  Mri -- real part of index of refraction relative to water
  Mrr -- imaginary part of index of refraction relative to water
  lambda -- wavelength in water in microns
  tjCabs: absorption cross section
  tjCbb: backscattering cross section
  tjCext: attenuation cross section
  tjCsca: scattering cross section
  tjF11: phase function
  tjG: average geometrical cross section over all orientations

Note: to compute efficiency factors simply devide the optical cross-section of interest by the geometerial cross section.
