Parameters for the atmospheric components of the transmission.

Parameter name	Component	Value (LAST)
^p	Rayleigh, H₂O, UMG	965
τ_a500	Aerosol	0.084 (free)
α	Aerosol	0.6
u₀	Ozone	300
p_w	H₂O	1.0 (free)
T	UMG	Measured

Notes. The surface temperature has no predefined value since it is measured on site at each image registration, and the values of τ_a500 and p_w are the nominal starting values before fitting it during the model opti-miziation. The value column shows the parameter nominal (or fixed) value for LAST.
