Determines the sample density for vesuvio based on sample transmission and composite masses
Example - VesuvioThickness
# Algorithm inputs
masses = [1.0079,27.0,91.0]
amplitudes = [0.9301589,2.9496644e-02,4.0345035e-02]
trans_guess = 0.831
thickness = 5.0
number_density = 1.0
# Run algorithm
dens_tbl, trans_tbl = VesuvioThickness(masses, amplitudes, trans_guess, thickness, number_density)
# Test output
print("The final density is: %.4f" % dens_tbl.cell(9,1))
print("The final transmission is: %.4f" % trans_tbl.cell(9,1))
Output:
The final density is: 24.4515
The final transmission is: 0.8310
