Hi, This maybe an odd question but does anyone know if there is a database or website where Light pollution data exists in bands?
In other words, light pollution say in the 450-500, 500-550, 550-600,.... nm bands. Obviously narrower band data (25nm would be better). I live in a city and have several LP filters with differing response curves. They all list the usual Hg and Na LP lines that they block but these days where LED lighting is unfortunately becoming ubiquitous it maybe more useful to know specific band information
