Dear Colleagues,

The ITRF93 related files are now available and could be downloaded by 
anonymous ftp using:

ftp schubert.ign.fr (192.33.147.230)

password:   your e-mail address

Move to the itrf directory ("cd /itrf"). The "ls" command gives the 
list of files.


General information files:

iers.site           : Catalogue of IERS sites
iers_dir.sta        : Directory of IERS stations
iers_sta.occ        : Occupancies of IERS stations


ITRF93 files: 

itrf93.txt          : Description of the ITRF93 solution

itrf93.ssc          : ITRF93 station coordinates at epoch 1993.0
                      ITRF93 velocity field
                      ITRF93N velocity field

itrf93.tp           : transformation parameters from ITRF93 to individual 
                      frames at epoch 1988.0
                      transformation parameters from ITRF93 to individual
                      frames at epoch 1993.0
                      rates of change of the transformation parameters
                      from ITRF93 to individual frames

iers_itrf93.ecc     : Local eccentricties for IERS colocation sites
                      (values used in the ITRF93 computation)
        

Other files:
