    153153 P = A + U ∗ (B − A)
     154
    154155 Q = D + U ∗ (C − D)
    155  X = P + V ∗ (Q − P )
     156
     157 X = P + V ∗ (Q − P)
    156158
    157159The values of U and V, which are within the range 0-1, are then used to weight the level-1 pixel values in the interpolation formula:
    158160
    159 f(X) = f(A) ∗ (1 − V ) ∗ (1 − U ) + f(B) ∗ (1 − V ) ∗ U + f(D) ∗ (1 − U ) ∗ V + f(C) ∗ U ∗ V
     161 f(X) = f(A) ∗ (1 − V ) ∗ (1 − U ) + f(B) ∗ (1 − V ) ∗ U + f(D) ∗ (1 − U ) ∗ V + f(C) ∗ U ∗ V
    160162
    161163where f(x) is the data value of cell x.
