Candidates with suspect distances from the Catalog of Nearby Stars were included in the Torino Observatory Parallax Program with the goal to clarify their membership in that catalog. Observations of the objects were made over the period 1996-2001 on the 1.05m Torino telescope. The trigonometric parallaxes and proper motions were determined using standard techniques. Of the 22 objects examined, 11 are within the 25pc horizon of the Catalog of Nearby Stars. The remaining objects are either misclassified, sub-dwarfs rather than main sequence dwarfs with consequently overestimated photometric distances, or objects with published trigonometric parallaxes that are incorrect.
