Listed parallax measurement is the trigonometric parallax of GJ 667(CCDM J17190-3459AB) as measured in the first reduction of HIPPARCOS. The value should be updated to the new one HIPPARCOS value (according to vizier) :
Parallax : 146.29 +/- 9.03
The same comment applies to the entries of GJ 667A and GJ 667B. Actually, Simbad contains and additional entry for the GJ 667AB binary which has the right plx (see CCDM J17190-3459AB).
To add a bit more confusion, Simbad also has an entry for the triple system (CCDM J17190-3459ABC) with little information.
Querying around GJ 667, there is a supposed 4th stellar companion to the system (CCDM J17190-3459D) that cannot be tracked back to any bibliographic source and probably doesn't exists (the star in the image of CCDM J17190-3459D does not have the same proper motion as GJ 667).
