Hi Adam,

I agree. At the minimum we should get whoever is “supplying”  positions to make sure the FRAME comment in the location.dat file is  a bit more informative – some current choice examples:

    FRAME='Approximate position of random GMRT antenna from Chris Phillips'
    FRAME='John Reynolds, priv. comm. 2015-01-12'
    FRAME='Kawaguchi - email 10June1997'

Where relevant, can we agree to (say) begin the FRAME line with “ITRFXXXX:”?

Copying this into the Vex file makes a lot of sense, but just getting folk to include the actual frame would be a good start.

Cheers
Chris
