Proposal Title: Tests of the Most Precise Pulsar Timing
ABSTRACT:
Recent high-precision pulsar timing data from pulsars J1713+07 and B1937+21 show that pulse arrival times
sometimes wander systematically over the course of a half-hour scan. The drifts, up to 0.5 microseconds, are
unexpected in such stable millisecond pulsars, and modestly larger than expected from simple scattering theory. To
characterize the trends more thoroughly, we propose long (rise-to-set), multifrequency observations of these sources.
