MAPPING OF THE PHASE DEPENDENCE OF LUNAR SURFACE BRIGHTNESS: REDUCTION OF THE OBSERVATIONS TO STANDARD CONDITIONS, CONSTRUCTION OF THE EQUIGONAL ALBEDO MAPS Kinematika Fizika Nebeshykh Tel, 1994, v.10, No 2, pp.56-64, by V.V.Korokhin, L.A.Akimov

The procedure is described of Lunar surface brightness observations using the photopolarimeter with one-dimensional CCD and personal computer. The algorithms are developed for initial processing of measurements, reduction of observations to standard conditions and construction of equigonal albedo maps. The maps will be used to construct the parameters maps of phase dependence of lunar surface brightness.

MAPPING OF THE PHASE PARAMETERS OF THE LUNAR-SURFACE BRIGHTNESS Astronomicheskii Vestnic, 1997, v.31, No 2, pp.143-152 [Solar System Research (Engl. transl.), 1997, v.31, No 2, pp.128-136], by V.V.Korokhin, L.A.Akimov

A technique for mapping the parameters of the phase dependence of lunar-surface brightness is described. The effect of the lunar relief on the brightness phase dependence is considered and a method for eliminating such an influence is proposed. The possibility of revealing the lunar relief from photometric observations is pointed out. The dependence of the so-called effective roughness coefficient on albedo is investigated. The possibility to determine the relative age of lunar formations from the analysis of roughness is demonstrated.

ZONING OF THE LUNAR SURFACE BY PARAMETERS OF BRIGHTNESS-PHASE RELATION Astronomicheskii Vestnic, 1997, v.31, No 6, pp.484-490 [Solar System Research (Engl. transl.), 1997, v.31, No 6, pp.430-435], by V.V.Korokhin

An analysis is done for distribution of parameters of brightness-phase relation over the lunar. For this purpose two-dimensional histogram (correlation diagram) diffuse albedo - effective roughness coefficient is constructed and analyzed. On the base of cluster analysis of this histogram, two-parameter zoning of the Moon's visible hemisphere is carried out. Also, the regions of lunar surface with extreme values of diffuse albedo and effective roughness coefficient are visualized. A possibility to estimate the degree of lunar-soil maturity from the analysis of the parameters of the brightness-phase relation is pointed out.
