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 = .0696 + .1107 cos A - .0383 sin A + .0662 cos C - .1185 sin C
y = .3429 - .0240 cos A - .1018 sin A - .1185 cos C - .0662 sin C
UT1-UTC = -.5401 - .00087 (MJD - 54756) - (UT2-UT1)
where A = 2*pi*(MJD-54748)/365.25 and C = 2*pi*(MJD-54748)/435.
TAI-UTC(MJD 54749) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54748)**0.80 S t = 0.00025 (MJD-54748)**0.75
