Blue lines show the abscissa and ordinate origins. For simplicity the region is centered on the reference point, but it could be anywhere allowed in the plane. <SPAN  CLASS="textbf">Top right</SPAN>: the same area is unprojected to $(&phis#phi;,&thetas#theta;)$ spherical coordinates on the 3D native sphere (the <SPAN  CLASS="textit">unprojection</SPAN> kind chosen for this example is not detailed here). The equator and zero reference meridian are shown in green. In this example, the fiducial point $(&phis#phi;_0,&thetas#theta;_0)$ has coordinates $(0,0)$. <SPAN  CLASS="textbf">Bottom left</SPAN>: the whole sky orientation is kept the same as before, but the coordinate system represented is now the 3D celestial sphere, with arbitrary reference point and inclination angle for the example. The equator and zero reference meridian are shown in red. <SPAN  CLASS="textbf">Bottom right</SPAN>: Same as previous plot but the celestial sphere is rotated and displayed with its origin of coordinates in front.

Blue lines show the abscissa and ordinate origins. There is no transformation possible to go to a native sphere in the CG02 formalism. <SPAN  CLASS="textbf">Top right</SPAN>: the reference point is shifted to the Equator, <EM>i.e.</EM> by a $&delta#delta;_0$ shift ($30^&cir#circ;$ in this example).
