Hi Jedm that's very interesting, and I'm glad to know about it. For completeness's sake, I'll develop two other (related) hypothesis regarding the origin of these variations. Always trying to explain the reason for the phase shift:
If you recall my graphs related to this I made some months ago: <http://maurol.com.ar/decay_rates/velocity_distance.png>http://maurol.com.ar/decay_rates/halflife_bnl+Rx.jpg and http://maurol.com.ar/decay_rates/velocity_distance.png (reprocessed) The "X" component of the distance ("$3" in the graphs), and the "Y" component of the velocity ("$7" in the second graph), both closely match the bnl decay rate changes. After a careful orientation of the solar system inside the galaxy, I realized that "X" is the component of the distance that is in a direction almost perpendicular (~6 degrees of difference) to the galactic center, on the plane of the ecliptic. And "Y" is then almost pointing to the galactic center. Always on the plane of the ecliptic. As the plane of the ecliptic is tilted 60 degrees with respect to the plane of the galaxy, when X is negative we're closer to the galactic plane, and when positive we're farther from it. And when the Y velocity component is positive, we're traveling almost towards the galactic center, and when negative, we're travelling away from it. What does this mean in relation to the decay rate changes? It could mean two things: 1) Closeness to the galactic plane increases the decay rates. 2) Moving away from the galactic center does it, and is related to how fast the movement is. Or both effects acting together. I'll now reproject the components of the distance and velocity as if exactly viewed from the galactic center, to see if a better match in phase is achieved.
