Argument Definitions (+ indicates altered content)
INTEGER            IL
REAL               FGO,        FMHZ,       FSET
Description
    THIS ROUTINE IS THE STANDARD PROBABILITY EVALUATION FOR THE 
    PROGRAM. THE DISTRIBUTIONS ARE SET IN SUBROUTINE CURMUF 
 
 
 EVALUATE THE PROBABILITY THAT THE OPERATING FREQUENCY IS GREATER 
THAN THE FOT, MUF OR HPF FOR A GIVEN LAYER USING THE MUF DISTRIBUTIONS 
    PRBMUF = 1. - FNORML(Z) 
 
 FMHZ IS THE OPERATING FREQUENCY 
 FGO IS THE MUF AT A SET ANGLE FOR A PARTICULAR LAYER, FOR ONE HOP 
     (IT MAY NOT BE THE CIRCUIT MUF) 
 FSET IS WHERE MEDIAN OF DISTRIBUTION IS PLACED (=FOT, MUF OR HPF) 
 IL IS LAYER (E, F1, F2 OR ES) 
 SIGL(IL) IS THE LOWER DECILE 
 SIGU(IL) IS THE UPPER DECILE
