An accurate fluorescence efficiency of the CS(0,0) band and the lifeti
me of CS have been calculated at 1 AU heliocentric distance. Model-ind
ependent CS column densities and production rates are determined from
derived fluorescent emission rates (g-factors) and lifetimes for 15 co
mets: Austin (1982g), Borrelly (1980i), Bradfield (1979X), Crommelin (
1983n), Encke (1980), Encke (1984), Giacobini-Zinner (1984e), Halley (
1982i), IRAS-Araki-Alcock (1983d), Meier (1980q), Panther (1980u), Ste
phan-Oterma (1980g), Tuttle (1980h), West (1975n), and Wilson (19861).
