Abstract
Rotated reflectance analysis of vitrinite macerals under the microscope is a valuable tool used by coal petrographers to determine the rank of coals. The analysis is subject to several sources of errors that the petrographer must be careful to avoid. This paper describes a computer aided analysis procedure that detects many errors that affect 4 4i reflectance results during rotation of the specimen under the microscope
