                   TRFXform7Tuple

7-Tuple (tx, ty, tz, s, sx, sy, sz) of conversion parameters with translations tx, ty and tz in milli-meter, scale s in ppB and rotations sx, sy and sz in milli-arc-seconds. For rates all are units-per-year.

Note: The parameters are also named as (Tx, Ty, Tz, D, Rx, Ry, Rz) or (T1, T2, T3, D, R1, R2, R3).
