Additional Instructions:
Need only "pulse-timing" runs - just long enough to accurately define the phase of their pulses. Usually that means 1-2 hours are enough - assuming that the star is reasonably bright, the period reasonably short, and the amplitude reasonably high. For stars failing on one or more of these criteria, a tad longer would be nice. We especially seek beginning-and-end-of-observing-season time series. These observations are harder to get, but they nail down the cycle count between seasons, which allows derivation of the long-term (over many years) period change - which in turn permits measuring the accretion torque on the underlying magnetic white dwarf.
