Dear all,

I have chosen this approach when updating the sitelog (which should 
be available soon on IGN's website), because we must keep track of 
such changes. See the attached partial sitelog.
I left the same DOMES number for both points since Zuheir seemed 
reluctant to change it.

If this is OK with ACs I will publish the sitelog as is, and I will 
prepare a DORISmail on this topic.

Best regards,

Hervé

    Solution : ITRF2000 (connection with the IGS station HARK)
    Epoch    : 1997.0

    X = 5084653.326 m     Y = 2670347.176 m     Z = -2768470.965 m
    Sig X = 0.003 m         Sig Y = 0.002 m         Sig Z = 0.002 m

    VX =  -0.0012 m/y        VY =  0.0198 m/y        VZ =  0.0159 m/y
    Sig VX = 0.0005 m/y     Sig VY = 0.0003 m/y     Sig VZ = 0.0004 m/y
