MJD = Julian Date - 2 400 000.5 days
UT2-UT1 = 0.022 sin(2*pi*T) - 0.012 cos(2*pi*T)
- 0.006 sin(4*pi*T) + 0.007 cos(4*pi*T)
where pi = 3.14159265... and T is the date in Besselian years.
TT = TAI + 32.184 seconds
DUT1= (UT1-UTC) transmitted with time signals
= -0.2 seconds beginning 14 June 2007 at 0000 UTC
Beginning 1 January 2006:
TAI-UTC(BIPM) = 33.000 000 seconds
**********************************************************************
* As of Bulletin A Vol. XX, No. 029, on 19 July 2007, we have *
* incorporated the igu00p01 solution into the combination. Note *
* that it will only be used to extend the IGS Rapid solutions. *
* The effect appears to be less that 0.1 mas in polar motion. *

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 = .0636 + .0281 cos A + .0819 sin A + .1301 cos C - .0506 sin C
y = .3464 + .0750 cos A - .0267 sin A - .0506 cos C - .1301 sin C
UT1-UTC = -.1629 - .00096 (MJD - 54305) - (UT2-UT1)
where A = 2*pi*(MJD-54300)/365.25 and C = 2*pi*(MJD-54300)/435.
TAI-UTC(MJD 54301) = 33.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-54300)**0.80 S t = 0.00025 (MJD-54300)**0.75
