Several of these will be included with daily reports over the next few days. For example, the figure with today's report shows Earth out-of-plane angle and sub-Earth latitude on Mars.

Earth out-of-plane angles larger than about 60 degrees correspond to times when there are no occultations and sensitivity to cross-track gravitational perturbations is maximum. Out-of-plane angles near 0 give diametric occultations and maximum sensitivity to vertical gravity. Positive Earth latitude means Mars' north pole is tilted toward Earth." Figures ======= Plot(s) illustrate some of the points made in the text. Each plot is a PostScript file, created and printable on our SOPC. For report text file HEAydddC.TXT Figure N will be labeled HEAydddC.PSN and sent as the N+1st e-mail message of a set. We assume that you can strip off the e-mail headers and either display or print copies of the figures on a machine in your area. People who have indicated that they cannot handle these files by e-mail are not included in the e-mail distribution of figures.
