Updates for SOFA Release 14 : 2017 December 4 - - - - - - - - - - - - - - - - - - - - - - - Summary of Changes ------------------ The changes fall into the following categories: 1. Change in the copyright status of the DAT routine. 2. Implementation of two new categories of routines, viz: a) There are three routines for the horizon/equatorial plane coordinates. b) There are six routines dealing with gnomonic (tangent plane) projections. 3. Due to introducing these new routines, The Astrometry Tools Cookbook, the test program and other supporting files have also been updated. 4. Other minor documentation/typographical corrections to various files. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + FORTRAN Library ---------------- 1 iau_DAT.for Code now classified as "user-replaceable support routine".
