AJ4072.Formal positional accuracy estimates are not available for this CORS
AJ4072.because its coordinates were determined in part using modeled
AJ4072.velocities. Approximate one-sigma accuracies for latitude, longitude,
AJ4072.and ellipsoid height can be obtained from the short-term time series.
AJ4072.Additional information regarding modeled velocities is available on
AJ4072.the CORS Coordinates for MYCS2 web page:
AJ4072.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
AJ4072
AJ4072.The coordinates were established by GPS observations
AJ4072.and adjusted by the National Geodetic Survey in March 2006.
AJ4072
AJ4072.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
AJ4072
AJ4072.The coordinates are valid at the epoch date displayed above
AJ4072.which is a decimal equivalence of Year/Month/Day.
AJ4072
AJ4072.Due to the release of the International GNSS Service (IGS) 2014
AJ4072.realization of the International Terrestrial Reference Frame of 2014
AJ4072.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ4072.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ4072.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ4072.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ4072.currently published epoch of 2010.00.

AJ4072.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ4072
AJ4072.The ellipsoidal height was determined by GPS observations
AJ4072.and is referenced to NAD 83.
