This program computes scattering coefficients using Mie theory, v1.04
Available options are: -h  = -help  print this message and quit
                       -q  = -quit  quit immediately
                       -L=[wavelength of incident light in nm]
                       -SR-=[SIGMA_RANGE_MINUS]  range of integration
                             below average radius, in ln(GSD)'s
                       -SR+=[SIGMA_RANGE_PLUS]   same above it
                             default is SR-= 3, SR+= 7
                       -STEPS=[MAX_STEPS] number of integration steps
                             default is STEPS=600
                       -n    use formulae for the refractive index
                            (additional info in the input file needed)
                       -u = -usage description of data sets and output
                       -d[debug code] - invokes step by step execution
                       -sm   suppress auxiliary messages
                       -zm   kill all messages, but the result line
                       -v    ask for mass densities of the components
                       -ice  show a_all, that includes a contribution
                             to a(L) from the ice, and b_e=b(1-g)
                       -th=[scattering angle in degrees]  for S11
                       -ct=[cos of the scattering angle]  for S11
                       -ex   print an example of an input file
                       -a    allow execution of external commands
