Hi Kevin,
I think the “type wrong” is Brian Skiffs comment against the reference. G8III and K0III are very close but your K0III reference (and your own confirming spectrum of course !) is missing from Brian’s catalogue so it could be worth letting him know so he can add it.
Here’s another oddity currently under investigation (BD-1 2458 referenced as G0v in the literature but clearly much hotter from a preliminary spectrum). Even visually the colour looks obviously wrong for the catalogued classification so it is not clear what is going on here.
