"On September 6, 2011 NGS's CORS group released revised coordinates for all CORS sites...NGS is in the process of completing an adjustment of the passive control network. Until the adjustment is complete, OPUS will allow users to choose getting coordinates in either the new or previous reference frames. Once the passive network is adjusted to NAD 83(2011, MA11, PA11) then the OPUS support for ITRF00 and NAD 83(CORS96, MARP00, PACP00) will end."
