And can you explain how this is done? What I mean is: are you superimposing opposite limbs onto each other (so calibrating the sextant at the sun's/moon's diameter), or the same limbs (so calibrating for zero at two spots in your field of view)? I take it it is the latter method. Do you have any data supporting the effectiveness?
