Abstract

We report the simultaneous observations in optical (CTIO) and X-ray (RXTE) for PSR B540-69 on November 12, 1996 which reveal that there is a "shift" in the phase-folded light curves. The shift is ∼ 17% of the 50 msec pulsar period and the optical pulse arrives earlier than the X-ray pulse. The uncertainty of better than 0.10 msec in our analysis of Crab pulsar arrival times proves that the detected ∼ 17% offset in the optical pulse of PSR B0540-69 is real.
