DEFINITION: (TBD)

Nine fields separated by blanks - one result per line:

1           MJD     Modified Julian Date 
2           TX      in mm
3           TY      in mm
4           TZ      in mm
5           S       scale in ppb = 10-9
6           sigTX   uncertainty of TX in mm             0. if NA
7           sigTY   uncertainty of TY in mm             0. if NA
8           sigTZ   uncertainty of TZ in mm             0. if NA
9           sigS    uncertainty of scale in ppb = 10-9  0. if NA
