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 |

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.
