PREDICTIONS:
The following formulas will not reproduce the predictions given below,
but may be used to extend the predictions beyond the end of this table.
x = .0748 + .1102 cos A + .0513 sin A + .0976 cos C - .0094 sin C
y = .3526 + .0575 cos A - .0960 sin A - .0094 cos C - .0976 sin C
UT1-UTC = -.4881 - .00082 (MJD - 54693) - (UT2-UT1)
where A = 2*pi*(MJD-54685)/365.25 and C = 2*pi*(MJD-54685)/435.
TAI-UTC(MJD 54686) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54685)**0.80 S t = 0.00025 (MJD-54685)**0.75
