This is the index page for the Gnomonic (tangent plane) Projections section of the Astronomy Library for SOFA Library Issue 2021-05-12 for Fortran 77. The Gnomonic (tangent plane) Projections section includes the following routines:
| TPORS | — | Solve for tangent point, spherical |
| TPORV | — | Solve for tangent point, vector |
| TPSTS | — | Project tangent plane to celestial, spherical |
| TPSTV | — | Project tangent plane to celestial, vector |
| TPXES | — | Project celestial to tangent plane, spherical |
| TPXEV | — | Project celestial to tangent plane, vector |
