T - universal time ( TDT - UT1 = 66.0 s );
s - the angular distance between the centers of the Moon and the shadow;
d - the linear distance between the Moon's center and that of the shadow
in terms of the shadow's radius;
P - the position angle of the Moon's disk semi-diameter directed towards
the shadow's center.
n terms of the shadow's radius;
P - the position angle of the Moon's disk semi-diameter directed towards
the shadow's center.
