The REF value in the user-defined correction table is entered when you press F•4 18% REF-
SET on the f Stop display.
For example, if you use the left-hand table shown below and press F•4 18% REF-SET when
the luminance value at the intersection of the cursors is 416 (10-bit value), the f Stop value
at that point (3.0) is displayed as the REF value.
