VizieR Online Data Catalog: A comparison of centering in ISS astrometry (Zhang+, 2021)

We provide the Cassini ISS astrometric reduction of the Saturnian satellite Anthe. The observations were taken from 2008 to 2017. Observation residuals were compared to JPL ephemerides SAT393.

Astrometric observations of Cassini's Imaging Science Subsystem (ISS) Narrow Angle Camera (NAC) and Wide Angle Camera (WAC) of Anthe.

The NAC's field of view is ~0.35 degree with a resolution of ~1.2354-arcsec/pixel. Image size is 1024x1024. The WAC's field of view is ~3.5 degree with a resolution of ~12.354-arcsec/pixel.

Image size 1024x1024. 112 NAC and 80 WAC observations of Anthe are provided. Positions in right ascension and declination, camera's pointing vector orientation, image positions with phase correction in sample and line (in pixels) and phase error in sample and line are given in the table. The methods for astrometric reduction of Anthe are well described in paper. Anthe's astrometric positions are given in ICRF reference frame centered on Cassini spacecraft.
