109 Experimental compensation for filters on light the pollution calculation are a bit tricky.
110 Part 1...
111
112 An unfiltered camera may include some IR and UV, and be able to read a bandwidth of say 360nm (at a reasonably high QE %).
113
114 But for simplicity, the filter compensation calculation will be based on the range for visible light, and use a nominal
115 bandwidth of 300, (roughly the bandwidth of a typical luminance filter).
116
117 The filter compensation factor that will be applied to light pollution will be the filter bandwidth (from the UI) / 300.
118 This means that a typical luminance filter would produce a "nuetral" compensation of 1.0 (300 / 300).
119
120 But the user interface will allow selection of wider bands for true "unfiltered" exposure calculations. Example: by selecting a
121 bandwith of 360, the light pollution compensation will 1.2, calculated as (360 / 300). This is to recognize that light pollution
122 may be entering the IR and UV range of an unfiltered camera sensor.
123
124 A Luminance filter may only pass 300nm, so the filter compensaton value would be 1.0 (300 / 300)
125 An RGB filter may only pass 100nm, so the filter compensaton value would be 0.3333 = (100 / 300)
126 An SHO filter may only pass 3nm, so the filter compensaton value would be 0.0100 = (3 / 300)
127
128 Filters will reduce bandwidth, but also slightly reduce tranmission within the range that they "pass".
129 The values stated are only for demonstration and testing purposes, further research is needed.
