Hi Joshua,
I am not sure about this. I need to check with Paul to see if this is valid.
Valid? Other than the patch he submitted appeared to not take into
account a decimal place, there's nothing invalid about the suggestion.
I probably should have tested that patch before submitting it. :) You are
correct that it needs to allow a decimal place.
The regular expression encompasses values that are generally agreed upon
to be civil/nautical/astronomical twighlight (i.e. dusk), plus when the
lower disk of the sun touches horizon at sea level, middle of the sun,
etc. Same for dawn. Other than these socially based standards, the same
equations work perfectly well for arbitrary angles of elevation.
Correct again. :)
