| Mean distance (km) | Eccentricity | Inclination (°) | W (°) | w (°) | Time & day of pericenter |
| 9675.00 | 0.003018 | 1.0590 | 88.647 | 116.354 | 6:02:25, 21/3/1989 |
Special corrections
- Dark current file: fond2103.dg3
- Gain = 3
- Focal plane temperature = -77.0 °C
- Shift in coordinates: Dlong = 0.0°, Dlat = 0.9°
- This is the only Mars session acquired in gain 3. The gain coefficients are derived from this session, and could be in error at short wavelengths due to a different amount of atmospheric scaterring in the data.
- Saturation and non-linearities occur in several channels in the short wavelength range, for even channels (see DocISM.pdf). The result of the usual data calibration is provided in ASCEVEN.CA0. Interpolated values for even channels are provided in ASCEVEN.CAL and ASCEVEN.ATM.
