The first several lines immediately after Eq. (9) should read as follows: " where ?, , £2» ^3 are direction cosines of the south galactic pole, expressed in earth equatorial coordinates. The corresponding geometry is shown in Fig. 5." The last sentence on p. 76 should read as follows: "These results are a measure of the long-term orbit decay rate. Average decreases at higher inclination, similar to the result found in Ref. 1 for planar oriented solar arrays."
