Detailed Description

Calculates solar insolation on a tilted plane of a spherical body.

This submodule computes the incoming solar flux based on:

• Latitude of the surface point
• Declination of the body
• Slope angle of the plane
• Azimuth of the topographic gradient
• Heliocentric distance
• Surface albedo

The calculation uses a sinusoidal variation to approximate day-night cycles and is based on Schörghofer N. (2025). Planetary Code Collection. flux_noatm.py.

Key Features:

• Accounts for local slope and orientation of the surface.
• Adjusts for heliocentric distance (inverse square law).
• Includes albedo effect to compute absorbed solar flux.
• Updates flux at initialization and every timestep.

Template Parameters

T	Numeric type used in the simulation (e.g., float, double)
