xxxx_A.txt File Format

The format of the xxxx_A.txt files is as follows:
           YYYY DDD X isWithinTolerance X(m) Y(m) Z(m) sigmaX(m) sigmaY(m) sigmaZ(m)
where: 
   - xxxx: 4-character station ID
   - YYYY: 4-digit year
   - DDD: 3-digit day of year
   - X: reserved
   - isWithinTolerance: 0 if the solution of this YYYY:DDD day is within tolerance; otherwise 1.
   - X Y Z: ITRFxx position in meters
   - sigmaX sigmaY sigmaZ: position uncertainties in meters

Example:
            2018 343 X 0   -113403.0140  -5504361.2980   3209404.1780    0.0010    0.0010    0.0040

Notes:
   - These files are computed on daily basis, with 2 days latency.
   - All positions in the ../opus/coord_14/ directory are referenced in the ITRF2014.
   - ../opus/coord_14/0000_file_list.txt contains the list of all position files availalbe in this ../opus/coord_14/ directory
