Parallax and distance error? edit

There's no way that the distance/parallax values listed in the article are accurate, considering the apparent magnitude. If they were, then the star would have an absolute magnitude of about 8.48, placing it in the unoccupied region of the HR diagram between the white dwarfs and A-type main sequence stars (given the A-type spectrum and ~7700 K temperature). Assuming it's an RV Tauri variable, it should be somewhere between absolute magnitudes -3 and -5, and MUCH more distant. Is there a better source for these values out there? --203.173.28.95 (talk) 08:00, 30 August 2015 (UTC)Reply
