hi,
i have (X,Y,Z) coordinates of a GPS receiver mounted on a telescope.which apparently forms half of a sphere.as GPS data are not 100% precise thus i cant get accurate surface of the half sphere. therefore i need to fit the points on the sphere. how do i get the best fit sphere and center of it.

regards
taaj
