Subject: errata for alg2001

Dear Peter M. Schwartz,

I have a minor ``astronomical'' contribution to the Errata part of the
Advanced Lighting Guidelines 2001:

concerning the illumination by the Moon,
p. 2-3, ref. 2.1.1.

Lunar illumination is an order of magnitude lower,
not 1 to 10 lux,
but up to perhaps 1 lux (the upper limit requires snow and suitable
clouds with a hole for the full Moon itself,
without them, 0.3 lux is an exceptional maximum).

I have adapted my programme planet to compute illumination by celestial
bodies as well two months ago, see mail archives

and
   Linkname: [Darksky]Re: Moon Light
        URL: http://amper.ped.muni.cz/darksky/a/msg00021.html

Values for the Moon given by thge programme are not very accurate, but
errors should be definitely below 20 per cent around full moon.

with best regards
(and much thanks for the downloadable version of the Guidelines)
