Astronomy question: When you referred to "G-231", did you actually intend to refer to "Gliese 231"(AKA Alpha Mensae)
? I've seen the "G" prefix applied to stars listed in both the Gliess(-Jahreiss) and Giclas catalogues over the years, so there's a possibility of confusion there.
I don't recall what led me to pick that designation, so I'm not really sure. (it's been a year!)
