xmtog_ak_rr_g()

subroutine pesg::xmtog_ak_rr::xmtog_ak_rr_g	(	real(dp), intent(in)	a,
		real(dp), intent(in)	k,
		real(dp), intent(in)	plat,
		real(dp), intent(in)	plon,
		real(dp), intent(in)	pazi,
		real(dp), intent(in)	delx,
		real(dp), intent(in)	dely,
		real(dp), dimension(2), intent(in)	xm,
		real(dp), intent(out)	lat,
		real(dp), intent(out)	lon,
		logical, intent(out)	ff )

For an ESG map with parameters, (A,K), and geographical orientation, given by plon,plat,pazi (radians), and given a point in grid-space units as the 2-vector, xm, return the geographical coordinates, lat, lon, (radians) of this point.

If instead the transformation is invalid for any reason, then return the raised failure flag, FF=.true.

Parameters

[in]	a	parameters of the ESG mapping
[in]	k	parameters of the 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 the orientation of the mapping at its center
[in]	delx	central x-spacing of the grid in radians
[in]	dely	central y-spacing grid point in radians
[in]	xm	grid-space 2-vector coordinates of a point to be mapped
[out]	lat	radians latitude of the point
[out]	lon	radians longitude of the point
[out]	ff	failure flag

xmtog_ak_rr_m()

subroutine pesg::xmtog_ak_rr::xmtog_ak_rr_m	(	real(dp), intent(in)	a,
		real(dp), intent(in)	k,
		real(dp), intent(in)	plat,
		real(dp), intent(in)	plon,
		real(dp), intent(in)	pazi,
		real(dp), dimension(2), intent(in)	xm,
		real(dp), intent(out)	lat,
		real(dp), intent(out)	lon,
		logical, intent(out)	ff )

Given the ESG map specified by parameters (A,K) and geographical center and orientation, plat,plon,pazi (radians), and a position, in map-space coordinates given by the 2-vector, xm, return the geographical coordinates, lat and lon (radians).

If the transformation is invalid for any reason, return instead with a raised failure flag, FF= .true.

Parameters

[in]	k	parameter 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 orientation of the mapping at its center
[in]	xm	center-relative 2-vector map space coordinates of a point
[out]	lat	radians latitude of the point
[out]	lon	radians longitude of the point
[out]	ff	failure flag
