Robert,
On p.213, Chapter 6 of GWW, you point out that latitude and altitude are important to the experiments of MM, MG, DM, GS and others.
What was the latitude for the 4 km/s (average) aether drift?
Am I right in thinking that this drift was W->E?
For the aether to revolve in one sidereal day, it's speed at the equator would be 0.464 km/s, which is more than 8.6 x slower than measured and more like 10 x slower when latitude is taken into account. I would appreciate your thoughts on this.
Neville.
