Abstract
- Table 2: Mean (ν) and standard deviation (σ) on separation s and position angle p (multiplied by the separation) in seconds of degrees for each satellite. N is the number of observations by satellite (one number per coordinate). The year appearing next to each observatory name corresponds to the observed Mars opposition. Table 3: Mean (ν) and standard deviation (σ) on right ascension and declination in seconds of degrees for each satellite. }N} is the number of observations by satellite. Table 4: Mean (ν) and standard deviation (σ) on right ascension and declination for each satellite. Both angles are multiplied by the distance spacecraft-moon to obtain kilometers. }N} is the number of observations by satellite. In the Pasewaldt et al. (2015) publication positions of Phobos have been determined using control point (CP) and/or limb point (LF) measurements. The former are based on the satellite's control network, a set of identifiable surface features well-distributed over the body's surface and defining its reference system. Recent MEX SRC measurements have been distinguished into observations made during linear and non-linear pointing variations. If the observations' pre-fit residuals deviated by more than three sigma from the mean value, they have been additionally categorised as an outlier. In case of only a few outliers it could not be clarified whether they have been related to non-linear variations in pointing or not. Some measurements are based on fits of the shape model-derived limb to only very short limb point arcs in the image (see also subsection 3.2.1). Table 5: Mean (ν) and standard deviation (σ) on sample and line in pixel and kilometer for each satellite. }N} is the number of observations by satellite. MRO (single) gathers data where only one moon was observable at a time. Table 6: Initial conditions and related uncertainties of Phobos and Deimos in the ICRF after fit at initial epoch J2000 (Julian day 2451545.0). Units are }km} and }km/sec}. All digits have been kept for reproducibility of our results. (5 data files).
