FUNCTION fHtmXyzToEq

Convert Cartesian coordinates (x, y, z) to Ra, Dec

(x, y, z) will be normalized unless (x, y, z) is close to (0,0,0)
Parameters:
@x float, @y float, @z float, the cartesian normal vector
Returns single row table containing the values (ra, dec) select * from dbo.fHtmXyzToEq(0.0, 0.0, -1.0) gives: ra dec 0 -90
