Pagination or Media Count:
Areographic coordinates of 546 points of the surface of Mars derived from 2321 measurements on 32 drawings made in October and November 1958 are listed. Longitudes are corrected for phase effect. Probable errors are of the order of 1 degree or 60 km on Mars. Comparisons are made with longitudes derived from transit observations in 1939, 1941, and 1958. Reduction constants to a system of absolute longitudes are given.
