Spherical Coordinates [Astro*Index]A system of spatial coordinates which specifies the location of a point P by three quantities: Radius Vector (R), Longitude (L), and Latitude (B). (In some situations, the quantities are defined as Radius Vector, Colatitude, and Longitude.) The angles L and B serve to determine a point Q on a sphere, and the distance R specifies the radial distance from the centre of the sphere to point P (passing through point Q).
Spherical and Cartesian coordinates are related by the following formulae:
x  =  r  *  cos(B)  *  cos(L) 
y  =  r  *  cos(B)  *  sin(L) 
z  =  r  *  sin(B)  


r  =  sqrt(x2 + y2 + z2)  
L  =  atan2(y,x)  
B  =  atan(z,sqrt(x2 + y2) 
Different centers. Different inclinations.
