AB It has been calculated in up to one million directions in the skythe radiance produced by a single source of light in the 0.12 km- 527 km range and for different light source and observing sitealtitudes.Using these data, light pollution indicators’ discrete PointSpread Functions (PSF) were computed: radiance averagedover all the hemisphere, at 30° altitude, in the first 10° abovethe horizon, and horizontal irradiance. From the discrete PSFs,analytical PSFs were retrieved, permitting to obtain theindicators values in a much faster way compared to thetraditional path, with saving times of the order of 10⁴-10⁶. Asapplications, it has been evaluated the light pollution at all theworld’s major professional astronomical observatories andmaps of Iberian peninsula for all the studied indicators wereproduced.
