Improved luminosity model and albedo for Saturn

The globe of Saturn is brighter than previously reported as indicated by its absolute opposition magnitudes in the UBVRI band passes which are −7.080, −7.842, −8.914, −9.587 and −9.606, respectively. The geometric albedo in V is 0.501 and it peaks in the R filter at 0.567. The brightest apparent magnitude of the system in the V-band is −0.61 and the faintest is +1.31. The B–V color index can be as blue as +0.93 and as red at +1.12.
