Constructing a pulsar timing array
Abstract
Arrival time data from a spatial array of millisecond pulsars can be used (1) to provide a time standard for long time scales, (2) to detect perturbations of the earth's orbit, and (3) to search for a cosmic background of gravitational radiation. A polynomial time series representation for these three effects is first developed that is appropriate for analysis of the present data with its limited degrees of freedom. A pulsar timing array program is then described that has been established at the National Radio Astronomy Observatory 43 m telescope with observations of PSR 1620 - 26, PSR 181 - 24, and PSR 1937 + 21. The results cover a 2 yr period beginning in July 1987. The influence of global parameters - clock, earth location, and effects of gravitational radiation is discussed in the context of the polynomial model.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
