Under Development for the Next Edition
Here's some notes on things I hope to add to the Setterfield analysis in upcoming editions. As some components become available, I will probably post the results here first.

- I've been examining the USNO double star catalog for binary stars with high-precision (<0.01%) period determinations over a
long time span. Pointers to public datasets where this data might be available would be much appreciated. There are a few heavily studied spectroscopic binaries (black hole candidates like Cygnus X-1, and accreting pulsar systems) where orbital ephemeris data to the necessary precision may be available.
NEWS FLASH! July 12, 2006: I may have found a paper with some binary stars in an orbital period variability study, Period Change of Eclipsing Binaries from the ASAS Catalog.
- Extragalactic redshift data are readily available (Astronomer's Bazaar). Using Setterfield's functions of speed-of-light with cosmic age gives a 'lookback' time function that is not linear so combining it with his claim that c = k z will also not generate a linear distance vs. z plot (Hubble diagram). Just how large is this disagreement?
- Calculate the differential arrival time with the Ardavan pulsar model, using a pulse emission mechanism at the pulsar light-cylinder. As the speed of light deceases, the light-cylinder will move closer to the neutron star (and further from the observer). This will change the observed timing. Preliminary calculations suggest this will be period-dependent. While the Ardavan model is probably not applicable for most pulsar emission, it may explain some anomalous events.
