directional

Note

This is an optional struct that requires options.calc_directional & options.calc_ebal to be output and calculated

Calculated

calc_brdf()

psi, tto initialized in SCOPE.m are extended in calc_brdf()

options.calc_planck enables Lot_ calculation (disables of Lot and BrightnessT)

options.calc_fluor enables LoF_ calculation

variable	user
`noa`	`calc_brdf()`

Fields initialized in SCOPE.m (read from directional)

variable	units	type	description
noa	-	double	number of observation angles
psi	deg	[333 x 1] double	observation relative azimuth angles
tto	deg	[333 x 1] double	observation zenith angles
