Hold computed parameters for querying the Prague Sky Model.

Parameters:

  • theta (float | NDArrayFloat) – Angle between view direction and zenith in radians [0, pi].

  • gamma (float | NDArrayFloat) – Angle between view direction and sun in radians [0, pi].

  • shadow (float | NDArrayFloat) – Altitude-corrected shadow angle in radians [0, pi].

  • zero (float | NDArrayFloat) – Altitude-corrected zenith angle in radians [0, pi].

  • elevation (float | NDArrayFloat) – Sun elevation at view point in radians.

  • altitude (float | NDArrayFloat) – Observer altitude in meters.

  • visibility (float) – Meteorological range at ground level in kilometers.

  • albedo (float) – Ground albedo [0, 1].
