MAO/PSAP/M1 - low subum psap signal

Sub-micron PSAP signal was very low and oscillated with the trailer temperature. Problem 
could be related to high RH. Problem fixed when instrument was better insulated.

Use CLAP data

• Aerosol light absorption coefficient, nominal red wavelength at dry or reference
  RH(Ba_R_PSAP3W)
• Aerosol light absorption coefficient, nominal blue wavelength at dry or
  reference RH(Ba_B_PSAP3W)
• Aerosol light absorption coefficient, nominal green wavelength at dry or
  reference RH(Ba_G_PSAP3W)
