HD 113447: Despite the large revised Hipparcos parallax (216.62+-56.53 mas; 2007A&A...474..653V), other indicators suggest that this is a much more distant star. The original Hipparcos parallax was 2.95+-4.27 mas, and Finch+2016 measures a ground-based URAT parallax of -2.3+-10.4 mas. Given the spectral type (F3V,
1976MmRAS..82...69H
; F3IV/V,
1979RA......9..479C
; an F3V should have Mv ~ 3.1 mag), color (B-V=0.455+-0.015; ESA 1997), magnitude (V=8.75; ESA 1997), one would predict a spectrophotometric distance for a F3V of this brightness to be D ~ 135 pc. Hence the star should probably not be considered among the nearest stars, despite its large revised Hipparcos parallax.
