Extended Data Table 2 Timings of the ring events apart from those from the Danish telescope

From: A ring system detected around the Centaur (10199) Chariklo

  1. Because the Cerro Burek chord does not bring further constraints to our analysis, it is not listed here.
  2. *The fitted time for the middle of C1R, expressed as seconds after 00:00:00 utc, 3 June 2013, calculated assuming that rings C1R and C2R have widths and optical depths that are averages of the ingress and egress values from the Danish telescopes, that is, WC1R = 6.6 km, τN,C1R = 0.38, WC2R = 3.4 km and τN,C2R = 0.06, and that the radial separation between C1R and C2R is 14.2 km.
  3. †The number of fitted data points.
  4. ‡Obtained from non-detections of the rings (see text).
  5. §Confirms the ring detection at Bosque Alegre, but is not used in the fit of the ring orbits owing to larger error bars compared with the 1.54-m telescope.
  6. ∥The SOAR timings are probably affected by a systematic offset, and are not used in the fits of the ring orbits and Chariklo’s limb shape (see text).
