David Leverington claims to be measuring cost-effectiveness of astronomical observations, and your provocative headline, "Star-gazing funds should come down to Earth," shows that his conclusion can lead to important consequences (Nature 387, 12; 1997). But, as his Correspondence shows, he is really merely measuring the number of times various papers have been cited.
