Station position from ITRF96 (IERS)

The nominal editing criteria are summarized below:
Residuals above 10 cm are rejected right away (the residual maxmum is 10 cm).
Passes with range bias above 10 cm are rejected (labeled DEL).
Passes with time bias above 0.1ms are rejected (labeled DEL).

Adopted abbreviations:

S-ID          - Station ID number

starting time - beginning time of each pass per station

long
/pass         - duration of each pass, (min.)

obs
/pass         - the number of data in each pass

edited
  obs         - the number of data rejected

range
 bias         - range bias of each pass, (mm)

time
bias          - time bias of each pass, (us)

raw
rms           - root mean square of residuals for the obrit

prec
 est          - root mean square of residuals corrected with range bias
                                                         and time bias.

sat           - satellite ID.

   Residuals are summarized for the following 3-day arcs: wtd rms
