Notes. Our notation is such that the asteroid(s) on the left side of the semicolon are considered perturbers, while those on the right side are massless test asteroids. The reference values are weighted averages of previous literature values taken from the work of Carry (2012). The third column contains references that describe the encounters. We note that Galád & Gray (2002) opted not to publish some of these encounters in the referred paper, and such encounters were obtained from the authors’ website directly (http://staryweb.fmph.uniba.sk/index.php?id=2171). The fourth and fifth columns respectively denote the start and end date of the observational time span for the perturbing asteroid. For the test asteroids, we use all of the available astrometry within this timespan.
