The value for C20 has been replaced with a value derived from satellite laser ranging. No rate terms were modeled.

For additional details on the background modeling, see the CSR RL05 processing standards document available at http://icgem.gfz-potsdam.de/L2-CSR0005_ProcStd_v4.0.pdf (Bettadpur 2012).
