************************************************************************ IERS Message No. 310 August 05, 2016 ************************************************************************ SOFA software update for next leap second This notice is to inform users that an update to release 12 of the SOFA software library was released on 2016 July 29 at 15:30 UTC. This is a minor release and contains updates to the routines iau_DAT (dat.for) and iauDat (dat.c) to include the leap second to be applied on 2016 December 31. The test-bed routines t_sofa_f.for and t_sofa_c.c are updated to test this change. Other updates The routines iau_LDSUN (ldsun.for) and iauLdsun (ldsun.c) that calculate the deflection of starlight by the Sun have changed without affecting the results for normal use. The Astrometry cookbooks have been modified to take account of the updated routines. The version number of the SOFA Time Scale and Calendar Tools cookbook has also been corrected. See the SOFA website at http://www.iausofa.org for details of all changes. SOFA operates under the auspices of the International Astronomical Union (IAU) to provide algorithms and software for use in astronomical computing. The initiative is managed by an international panel, the SOFA Board, appointed through IAU Division A. SOFA works closely with all the Commissions of the Division and with the International Earth Rotation and Reference Systems Service (IERS).
