The Parallax of VHS J1256-1257 from CFHT and Pan-STARRS 1
  We present new parallax measurements from the CFHT Infrared Parallax Program
and the Pan-STARRS 3$\pi$ Steradian Survey for the young ($\approx150-300$ Myr)
triple system VHS J125601.92$-$125723.9. This system is composed of a nearly
equal-flux binary ("AB") and a wide, possibly planetary-mass companion ("b").
The system's published parallactic distance ($12.7\pm1.0$ pc) implies absolute
magnitudes unusually faint compared to known young objects and is in tension
with the spectrophotometric distance for the central binary ($17.2\pm2.6$ pc).
Our CFHT and Pan-STARRS parallaxes are consistent, and the more precise CFHT
result places VHS J1256-1257 at $22.2^{+1.1}_{-1.2}$ pc. Our new distance
results in higher values for the companion's mass ($19\pm5$ M$_{\rm Jup}$) and
temperature ($1240\pm50$ K), and also brings the absolute magnitudes of all
three components into better agreement with known young objects.
