96/01/29 10:31 DEFECT in program arcic
SYMPTOM: Kilometer level error in initial conditions on day before leap
second
PROBLEM: error interpolating UT1-UTC value at leap second
CORRECTION: Modified subroutines ieop (initialize storage arrays with EOP
values) and inteop (interpolate for EOP at epoch) to use
UT1-GPS internally rather than UT1-UTC. The advantage of
UT1-GPS is that neither time series has a leap second
discontinuity. Subroutine output is still UT1-UTC.
