CPU times

solar angle and albedo does not affect CPU time much, for mystic the CPU increases slightly with increasing surface albedo
for cases A to D, disort requires approx. 0.18 s per wavelength, for case E it is more efficient (0.078 s) since wavelength loop within uvspec (for aerosol/clouds it is currently not possible to put in optical properties data in required format).
for mystic 100.000 photons were used for each wavelength, CPU time estimated for cases A-D from calculation time for first wavelength in band (sza=10, albedo=0.05).
