This is the dataset for the article "Conductivities of Titan's dusty ionosphere", Journal of Geophysical Research: Space Physics, DOI: 10.1029/2021JA029910
Please see the article for the description and references for data derivations.
ephemerides.xlsx contents (one flyby per sheet):
UTC time stamp
altitude [km] altitude above Titan surface
sc_Velocity [km/s] magnitude of Cassini spacecraft velocity
Solar_Zenith_Angle [degrees] angle from the Sun direction (X-axis in solar ecliptic coordinates)
sub_solar_lat [degrees] of sub-solar latitude (i.e. Titan geographic latitude where Sun is in zenith)
Saturn_Local_time [hours] azimuthal coordinate of Cassini with respect to Saturn
Local_Time [hours] azimuthal coordinate of Cassini with respect to Titan
