Use a and k as the parameters of an Extended Schmidt-transformed Gnomonic (ESG) mapping centered at (pdlat,pdlon) and twisted about this center by an azimuth angle of pdazi counterclockwise (these angles in degrees).

Like hgrid_ak_rx, return the grid points' cartesians xc and Jacobian matrices, xcd. Garea, the area of each grid cell, is also returned as in hgrid_ak_rx, and a failure flag, ff, raised when a failure occurs anywhere in these calculations.

Parameters

[in]	lx	center-relative x grid index for left edge of the domain
[in]	ly	center-relative y grid index for lower edge of the domain
[in]	nx	numbers of the grid spaces in x
[in]	ny	numbers of the grid spaces in y
[in]	a	parameters of an ESG mapping
[in]	k	parameters of an ESG mapping
[in]	pdlat	degrees latitude of the projection center of the mapping
[in]	pdlon	degrees longitude of the projection center of the mapping
[in]	pdazi	azimuth of the orientation of the mapping at its center
[in]	delx	central x-spacing of the grid in radians
[in]	dely	central y-spacing of the grid in radians
[out]	xc	grid points' earth-centered unit cartesians
[out]	xcd	Jacobian matrices, d(xc)/d(xm)
[out]	garea	array of grid-cell areas (steradians)
[out]	ff	failure flag
