Values of aberration in the first and last measurements are dis-
played.
(3) Total HOA graph The horizontal axis shows the number of measurements and the ver-
tical axis the value of HOA (High Order Aberration).
The expression at the top right of the graph indicates the approxi-
mated primary line.
