*"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.
