Notes. (a) Inferred using geometric albedo of pV = 0.48
. Δvmin (from Ragozzine & Brown 2007 unless otherwise indicated) is the minimum of four possible solutions of velocity relative to the collision location’s orbit in a calculation where the information about the original orbital angles Ω, ω, and M has been lost. References to first detection of water ice confirming family membership, sources of thermal data: S for Spitzer Space Telescope and H for Herschel Space Observatory (the parentheses indicate that thermal data were not used in the size/albedo solution shown in this table). O17 = Ortiz et al. (2017), TW = This work, E10 = (Elliot et al. 2010). (b) The result of 2002 TX300 is from an occultation event re-analysed in this work (see Sect. 3.3). (c) This work.
