Comment :
Parameters Hapke of photometric model are published :
for satellite Io in
McEwen, A. S., Johnson, T. V. & Matson, D. L. 1988, Icarus, 75, 450
for satellites Europa, Ganymede and Callisto
in
Domingue, D. & Verbiscer, A. 1997, Icarus, 128, 49
Data reduced from MPC photometric data (Emel'yanov, Ural'skaya, 2011, Solar System Research, 45, 377).
Designations:
H - absolute magnitude in R band at solar distance 1 au, observer distance 1 au,
reduced at phase angle α=0°
according to the IAU two-parameter magnitude system
(see
Bowell et al., 1989)).
G - slope parameter according to the IAU two-parameter magnitude system (in R band).
V(1,1,6°) - absolute magnitude in R band
at solar distance 1 au, observer distance 1 au,
reduced at phase angle α=6° .
V0(6°) - visual magnitude in R band from the Earth at mean opposition
reduced at phase angle α=6° .
sigma - magnitude uncertainties (1σ)
(For some satellites H and G can not be determined from MPC photometric data.)

observer distance Δ, au,
phase angle α, deg .
H(1, 1, 0) - absolute magnitudes

H(1, 1, α) = V-5 log(rΔ)+2.5 log10
[(1-G)·Φ1(α) +G·Φ2(α)]

(Bowell et al., 1989).
HV, GV,
HR, GR,
HB, GB
are the values of H(1, 1, 0) and G

Satellites of Uranus
V0 - visual magnitude at 1 au from the sun and observer
V0min et V0max
are the maximum and minimum magnitude at 0 degrees
phase angle and at a subsolar latitude of -40 degrees.
Δm - the magnitude drop at 1 degrees phase angle.
Magnitudes from Earth at mean opposition distance are fainter by 12.71.
P - albedo geometric at 1 degrees phase angle.

Comment :
In (
Karkoschka, 2001
) following data are given
for the satellites U1 - U15, S/1986 U10 :
1. Parameters Hapke of photometric models.
2. Rotational lightcurves.
3. Phase functions.
4. Color Indices.
Data reduced from MPC photometric data (Emel'yanov, Ural'skaya, 2011, Solar System Research, 45, 377).
Designations:
H - absolute magnitude in R band at solar distance 1 au, observer distance 1 au,
reduced at phase angle α=0°
according to the IAU two-parameter magnitude system
(see
Bowell et al., 1989)).
G - slope parameter according to the IAU two-parameter magnitude system (in R band).
V(1,1,1°) - absolute magnitude in R band
at solar distance 1 au, observer distance 1 au,
reduced at phase angle α=1° .
V0(1°) - visual magnitude in R band from the Earth at mean opposition
reduced at phase angle α=1° .
sigma - magnitude uncertainties (1σ)
R[1] - visual magnitude in R band from the Earth published in
Sheppard et al., 2005
R[2] - visual magnitude in R band from the Earth published in
Maris et al., 2001
