Computes range- and phase-normalized visual magnitudes using a lambertian sphere phase function.

Parameters

• observed_magnitudes: Nx.Tensor of observed apparent magnitudes
• observed_phases: Nx.Tensor of phase angles in radians
• observed_ranges: Nx.Tensor of ranges
• std_range: Standard range for normalization (same units as observed_ranges)
• std_phase: Standard phase for normalization in radians

Returns

• Nx.Tensor of normalized magnitudes
