Notes. H is the absolute magnitude, S′ is the spectral slope, D is the diameter, pV is the visible albedo whereas σS′, σD and σpv are the uncertainties in spectral slope, diameter, and visible albedo, respectively. The data is obtained from the AKARI IRC asteroid flux catalog by Alí-Lagoa et al. (2018), and from the recent 2019 NEOWISE diameters and albedos archive, taken by the WISE Camera instrument of Wide-Field Infrared Survey Explorer (Wright et al. 2010).
