Description   Memoir 170 This work is intended as a supplement to the well known planetary, lunar & solar tables produced by Bryant Tuckerman (1962, 1964). Since these tables appeared--as vols. 56 & 59 of the Memoirs of the APS--they have continued to prove an invaluable aid to historians of astronomy. An important usage is the dating of ancient & medieval astronomical observations but the tables also have wide application in determining the accuracy of early measurements & calculations. This supplementary vol. owes its origin to the discovery by the authors of significant errors in Tuckerman’s tabular positions of Mars. They made a systematic comparison between Tuckerman’s positions for the Sun & planets & those computed from an integrated ephemeris. Only in the case of the longitude of Mars were errors found to be serious but these could amount to as much as 0.7 deg (considerably more than the Moon’s apparent diameter).
