isofit.surface.surface_thermal
- class ThermalSurface(full_config)[source]
Bases:
MultiComponentSurface
A model of the surface based on a Mixture of a hot Black Body and Multicomponent cold surfaces.
- xa(x_surface, geom)[source]
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.
- fit_params(rfl_meas, geom, *args)[source]
Given a reflectance estimate, find the surface reflectance
- calc_rfl(x_surface, geom)[source]
Reflectance. This could be overriden to add (for example) specular components
- drfl_dsurface(x_surface, geom)[source]
Partial derivative of reflectance with respect to state vector, calculated at x_surface.
- dlamb_dsurface(x_surface, geom)[source]
Partial derivative of Lambertian reflectance with respect to state vector, calculated at x_surface.
