This file was produced by Bill Taber on October 3, 1997. The values in this file are taken from the JPL Interoffice Memorandum (IOM 314.10-127 May 22, 1995) "JPL Planetary and Lunar Ephemerides, DE403/LE403" by Myles Standish, et al. The masses for the sun and planetary barycenters given in this file are derived from the masses used for the integration of the planetary ephemeris DE-403. In the ephemeris the values of the masses are given as ratios to of Solar GM to barycenter GM. These values are given here. BODY1_GMSUN/GM = 6023600.0 BODY2_GMSUN/GM = 408523.71 BODY3_GMSUN/GM = 332946.048134 BODY4_GMSUN/GM = 3098708.0 BODY5_GMSUN/GM = 1047.3486 BODY6_GMSUN/GM = 3497.898 BODY7_GMSUN/GM = 22902.98 BODY8_GMSUN/GM = 19412.24 BODY9_GMSUN/GM = 135200000.0 These values are used by other products that use DE-403 to provide gravitational force models for integration of trajectories. Given the mass ratios and the mass of the sun, you can compute the mass of any barycenter. These values are supplied in the text data given below. Note that the values provided are rounded to three decimal places. \begindata AU = 149597870.691 BODY1_GM = 22032.080 BODY2_GM = 324858.599 BODY3_GM = 403503.235 BODY4_GM = 42828.314 BODY5_GM = 126712767.863 BODY6_GM = 37940626.063 BODY7_GM = 5794549.007 BODY8_GM = 6836534.064 BODY9_GM = 981.601 BODY10_GM = 132712440023.310 \begintext The masses of bodies other than the earth and moon are simply taken to be the masses of the barycenters given above.
