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
= -0.4 seconds beginning 25 Sep 2014 at 0000 UTC

The contributed observations used in the preparation of this Bulletin
are available at <http://www.usno.navy.mil/USNO/earth-orientation/
eo-info/general/input-data>. The contributed analysis results are based
on data from Very Long Baseline Interferometry (VLBI), Satellite Laser
Ranging (SLR), the Global Positioning System (GPS) satellites, Lunar
Laser Ranging (LLR), and meteorological predictions of variations in
Atmospheric Angular Momentum (AAM).

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 = 0.1021 + 0.0560 cos A - 0.0255 sin A + 0.0195 cos C - 0.0494 sin C
y = 0.3485 - 0.0215 cos A - 0.0498 sin A - 0.0494 cos C - 0.0195 sin C
UT1-UTC = -0.3959 - 0.00102 (MJD - 56947) - (UT2-UT1)
where A = 2*pi*(MJD-56939)/365.25 and C = 2*pi*(MJD-56939)/435.
TAI-UTC(MJD 56940) = 35.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-56939)**0.80 S t = 0.00025 (MJD-56939)**0.75
