isofit.surface.surface_thermal

class ThermalSurface(full_config)

Bases: isofit.surface.surface_multicomp.MultiComponentSurface

A model of the surface based on a Mixture of a hot Black Body and Multicomponent cold surfaces.

xa(x_surface, geom)

Mean of prior distribution, calculated at state x. We find the covariance in a normalized space (normalizing by z) and then un- normalize the result for the calling function.

Sa(x_surface, geom)

Covariance of prior distribution, calculated at state x.

fit_params(rfl_meas, geom, *args)

Given a reflectance estimate, find the surface reflectance

calc_rfl(x_surface, geom)

Reflectance. This could be overriden to add (for example) specular components

drfl_dsurface(x_surface, geom)

Partial derivative of reflectance with respect to state vector, calculated at x_surface.

calc_lamb(x_surface, geom)

Lambertian Reflectance.

dlamb_dsurface(x_surface, geom)

Partial derivative of Lambertian reflectance with respect to state vector, calculated at x_surface.

calc_Ls(x_surface, geom)

Emission of surface, as a radiance.

dLs_dsurface(x_surface, geom)

Partial derivative of surface emission with respect to state vector, calculated at x_surface.

summarize(x_surface, geom)

Summary of state vector.
