Estimations made on the basis of reduction
of the photometric data published in the MPC (Emel'yanov, Ural'skaya, 2011, Solar System Research, 45, 377)
( See photometric parameters of sateliites in this database)
using the equation
(Bowell et al., 1989))
log pH=6.114-2 log(2r)-0.4 H ,
where r - radius of satellite,
H - absolute magnitude in R band at solar distance 1 au, observer distance 1 au,
reduced at phase angle α=0°, and pH - supposed albedo
in R band.
