摘要：Equation (9), representing the phase φ(t) at time t of a periodic variableundergoinga periodchange,is erroneous.This equation should instead read φ(t) = N E (t) − ?N E (t)?, (1) where N E (t) is the number of cycles elapsed at time t since a re- ference epoch E. The quantity N E (t) for a constant rate of period change is given by N E (t) = 1 β ln ? 1 + β P 0 (t − E) ? , (2) ? Based on observations collected at the Indian Astrophysical Observatory, Hanle, India. where β is the period change rate and P 0 is the period at the epoch E.
