Notes. All values considering a single object. ^(a)From independent photometric measurements. ^(b)Obtained from combining the corresponding H_V value with the occultation-derived D_eq ^(c)Fitted in the NEATM with p_V fixed from the occultation. ^(d)Not fitted, value fixed to the mean η of the TNO population.
