✦ Synopsis

A dozen lightcurves obtained during the ground-based observations of the occultation of 28 Sgr by Titan (3 July 1989) are reanalyzed. Profiles of density and temperature between altitude levels z 1 Partly supported by a grant from the Institut Universitaire de France.

of 290 and 500 km (pressures p from 110 to 1.4 Β΅bar) are derived. A mean number-density scale height of 50.5 Β± 1.4 km is found with no significant difference between immersion and emersion. Two inversion layers are observed at 425 and 450-455 km, respectively ( p ∼ 7 Β΅bar and p ∼ 4 Β΅bar), with an increase in temperature of about 10 K in less than βˆ†z = 10 km. These layers are visible both 357

We present optical depth profiles for Saturn's rings at wavelengths of 0.9, 2.1, 3.3, and 3.9 ¡m, obtained from the occultation of the star 28 Sgr on 3 July 1989 when the rings were near their maximum opening angle. The radial resolution of the data is ∼18 km, as set by the angular diameter of the s
