Abstract
ABSTRACT This study is based upon (1) the 445 papers published in 197. 76 by visiting and staff astronomers from observations with the two 0.44 , two 0.9-m, 1.3-m, and 2. 1-m telescopes at the Kitt Peak National Observatory, (2) the 4179 references (citations) made in 197. 7S to those papers, and (3) the relative annual operating costs for those telescopes. The intermediate results are that the numbers of published papers vary as the 1.1-power of the aperture, the numbers of citations vary as the 1.5-power of the aperture, and the initial costs and annual operating expenses vary as the 2.37- and 2.1-powers of the aperture, respectively. These indicate that smaller telescopes, properly equipped, are several times more productive of publications and citations than the largest one at Kitt Peak National Observatory considered in this study, the 2.1- m. Data are given on the average citation histories of papers for the first five years after publication and on the frequencies of highly- and little-cited papers from each telescope.
