+# At lighting L1 the Moon is drawn from the LRO Camera's map (scripts/fetch-moon.py),
+# dark maria against bright highlands, turned as it was at this epoch, as bright as the
+# real full Moon. At L0 it is a uniform gray sphere, about two thirds as bright. Either
+# way its edge is darker than a real full Moon's, which looks nearly flat out to the
+# limb.
