Let us here additionally collect the result of the transformation

by the following
Corollary
3.10
.
Corollary 3.10 (The change from one chart to another chart: cha-cha-cha, the surface normal
ellipsoidal longitude/latitude versus the oblique quasi-spherical longitude/latitude).
Given the longitude of the ascending node
Ω
as well as the inclination
I
of the oblique equatorial
plane, then the transformation of surface normal ellipsoidal longitude/latitude into oblique quasi-
spherical longitude/latitude is represented by (

).
End of Corollary.
of type oblique quasi-spherical longitude/latitude
are not orthogonal. Accordingly, the matrix of the metric of E

in terms of these coordinates
contains off-diagonal elements. Finally, we note that the terms up to order three of the corre-
sponding Taylor series expansions can be determined by resorting to the partial derivatives of
Box

.
It should be noted that the coordinates
