"then the general bivariate normal equation becomes the Hoyt distribution" is a bit misleading. The distribution of (h,v) coordinates is assumed to be bivariate normal. Then the Hoyt distribution is the (univariate) distribution of the distances (radial error) of each point to the true COI.

Likewise, "special case is the Rayleigh Distribution" should make more explicit that the Rayleigh distribution concerns the distances of each point to the true COI.

The same applies to the sentence "this distribution will be called the Orthogonal Elliptical Distribution. It is obviously a special case of the Hoyt distribution which in turn is a special case of the bivariate normal distribution."' - the Hoyt distribution is not a special case of the bivariate normal distribution.

You raise good points. The wording is a bit sloppy. I did glossed over the "true COI" which is something that ought to be discussed.

Actually I now realize that the wording isn't just sloppy, but seriously flawed.
