In the section 6.3.2 ”Ocean tide models”, part ”FES2004”, the phase of the C20 term of the very long period waves has been corrected to pi/2 and the corresponding changes are introduced in the first two data lines of the files fes2004.dat and fes2004_Cnm-Snm.dat. Note that a significant error is also corrected in the file fes2004_Cnm-Snm.dat: The unit of the coefficients is 10^-11 (erroneously was 10^-12). * Chapter 7 ”Displacement of reference points” has been updated on 23 September 2011, see http://tai.bipm.org/iers/convupdt/convupdt_c7.html . The subroutine ARG2.F has been corrected for a bug that caused an error for dates starting with year 2000. It is expected that the USNO web site http://maia.usno.navy.mil/conv2010/convupdt.html will be updated with a short delay.
