3. End point correlation line

ET = Total unadjusted error: maximum deviation between the actual and the ideal transfer curves.

EO = Offset error: deviation between the first actual transition and the first ideal one.

EG = Gain error: deviation between the last ideal transition and the last actual one.

ED = Differential linearity error: maximum deviation between actual steps and the ideal one.

EL = Integral linearity error: maximum deviation between any actual transition and the end point correlation

line.
