These angles may be calculated by calling the routine iau_PFW06. SOFA also supports the direct computation of the CIP GCRS X,Y by series, available by calling iau_XY06. In the ANSI C routine iauP06e for evaluating the equinox-based precession angles (IAU 2006) replace Notes: 5) with a similar set of comment lines as for the Fortran version, but noting that routines mentioned are iauPfw06 and iauXy06. af2a.c, Addition to comments. Insert another note that says 2011 May 24 af2a.for "If there are multiple errors, the status value reflects only the first, the smallest taking precedence." changes.lis and Documentation typographical error. 2011 Jan 04 changes.pdf In these files within the ANSI C release, the issue date in the first line of the files is given as 2012-12-01. The correct issue date is 2010-12-01. d2tf.c Documentation typographical error. 2011 May 24 Note 3) line 4, replace ihms[0]=24 by ihmsf[0]=24 dtdb.c Documentation correction. 2011 May 24 The first part of Note 1) should read ** 1) The date date1+date2 is a Julian Date, ... dtf2d.for and Typographical correction to comments. 2011 Apr 11 dtf2d.c In the comments for Fortran code the "Returned:" items JD1,JD2 should be D1,D2. Similarly, in the 2nd line of Note 7, JD1+JD2 should read D1+D2. The same issues exist in the C code except the variables are lower case. nut06a.for and Correction to comments. 2011 Apr 05 nut06a.c A correction to the wording of Note 3. It is necessary to replace the words "dynamical flattening" by "dynamical form factor J2", so that the last line reads "... secular variation in the Earth's dynamical form factor J2." sofa_ts_f.pdf and Documentation typographical error. 2011 Jan 04 sofa_ts_c.pdf In the SOFA Time Scale and Calendar Tools documents, a function called DTF is listed in Section 1.3 on page 1. The correct name of the function is D2TF. sofam.h Addition to comments. Insert the following 3 lines 2011 May 24 before the version date near the start of this ANSI C include file: ** Please note that the constants defined below are to be used only in ** the context of the SOFA software, and have no other official IAU ** status. tdbtt.c Documentation typographical error. 2011 May 24 Under "** Given:" replace comment dtb1,tdb2 double TDB as a 2-part Julian Date with tdb1,tdb2 double TDB as a 2-part Julian Date tdbtt.for Documentation typographical error. 2011 May 24 Under "* Given:" replace comment DTB1,TDB2 d TDB as a 2-part Julian Date with TDB1,TDB2 d TDB as a 2-part Julian Date tf2a.c Correction to comments. 2011 Apr 19 In the "Returned:" section replace the variable "days" by the variable "rad". tf2a.c, tf2a.for, Addition to comments.
