Notes. References to data from literature and databases are listed with N the total number of individual V - or R-band data points, the assumed phase coefficient is the average of TNO phase coefficients: 0.12 ± 0.06 (Perna et al. 2013), 
is the reduced χ2 describing the goodness of fit of the linear phase curve, HV is the absolute V -band magnitude with uncertainties taking into account light curve (L.c.) amplitude ΔmR. The default light curve amplitude is 0.2 mag (Duffard et al. 2009). The light curve uncertainty is added to targets that have Herschel data and taken into account as input HV in thermal modelling. V–R colours are from MBOSS-2 (Hainaut et al. 2012) unless otherwise indicated. The assumed V–R colour is the average of dynamically hot CKBOs from MBOSS-2: 0.51 ± 0.14. (a) Data from SLOAN’s r’ and g’ bands converted to V or R band. (b) Phase coefficient at R band. (c)Data inconsistent and would lead to a negative phase coefficient in a free fit. (d) Data limited to a narrow phase angle range and would lead to an implausibly high phase coefficient in a free fit. (e) Phase coefficient fit using 12 w-band data points from MPC in the phase angle range 0.3 < α <1.2. MPC: Minor Planet Center, http://www.minorplanetcenter.net/iau/lists/TNOs.html. References.
