Like hgrid_ak_rr_c except the argument list includes the earth radius, re, and this is used to express the map-space grid increments in the dimensional units, delxre, delyre on entry, and to express the grid cell areas, garea, in dimensional units upon return.

The gridded lats and lons, glat and glon, remain in radians.

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]	plat	radians latitude of the projection center of the mapping
[in]	plon	radians longitude of the projection center of the mapping
[in]	pazi	Azimuth of map orientation at its center
[in]	re	earth radius
[in]	delxre	map-space grid increments in the dimensional units
[in]	delyre	map-space grid increments in the dimensional units
[out]	glat	grid points for latitude
[out]	glon	grid points for longitude
[out]	garea	array of grid-cell areas in dimensional units
[out]	ff	failure flag

Like hgrid_ak_rr_c except the argument list includes the earth radius, re, and this is used to express the map-space grid increments in the dimensional units, delxre, delyre on entry, and to express the grid cell areas, garea, and the x- and y- grid steps, dx and dy, in dimensional units upon return.

The gridded lats and lons, glat and glon, remain in radians. Also, in order for the argument list to remain compatible with an earlier version of this routine, the relative rotations of the steps, dangle_dx and dangle_dy, are returned as degrees instead of radians (all other angles in the argument list, i.e., plat,plon,pazi,glat,glon, remain radians).

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	number of grid spaces in x
[in]	ny	number of grid spaces in y
[in]	a	Extended Schmidt Gnomonic parameter
[in]	k	Extended Schmidt Gnomonic parameter
[in]	plat	latitude of projection center of the mapping (radians)
[in]	plon	longitude of projection center of the mapping (radians)
[in]	pazi	Azimuth of map orientation at its center (radians)
[in]	re	earth radius in dimensional length units
[in]	delxre	map-space grid increments in the dimensional units
[in]	delyre	map-space grid increments in the dimensional units
[out]	glat	gridded lats (radians)
[out]	glon	gridded lons (radians)
[out]	garea	grid cell areas in dimensional units
[out]	dx	x- grid steps in dimensional units
[out]	dy	y- grid steps in dimensional units
[out]	dangle_dx	azimuth rotations of the steps dx (in degrees)
[out]	dangle_dy	azimuth rotations of the steps dy (in degrees)
[out]	ff	failure flag
