For a parameter vector, ak and a map-space domain-parameter vector, ma, return the lambda-parameterized quality diagnostic, Q, and the geographic domain-parameter vector ga.

Lambda is given by lam <1. Also, return the derivatives, qdak and qdma, of Q wrt ak and ma, and the derivatives gadak and gadma, of ga wrt ak and ma.

The domain averages of Q are accurately computed by bi-Gauss-Legendre quadrature over the positive quadrant of the domain (exploiting the symmetry) of the four constituent terms, v1, v2, v3, v4, from which the mean Q is computed using a quadratic formula of these constituents. The number of Gauss points in eaxh half-interval is ngh, and the nodes themselves are, in proportion to the half-interval, at xg. the normalized gauss weights are wg.

If a failure occurs, colmputations cease immediately and a failure flag, FF, is raised on return.

Parameters

[in]	ngh
[in]	lam	Lambda
[in]	xg
[in]	wg
[in]	ak	parameter vector
[in]	ma	map-space domain-parameter vector
[out]	q	lambda-parameterized quality diagnostic
[out]	qdak	derivatives value
[out]	qdma	derivatives value
[out]	ga	geographic domain-parameter vector
[out]	gadak
[out]	gadma
[out]	ff	error flag
