Surprising object type for a paper

[DougBurke]

I was surprised to see an object type of "GlCl ~" be listed for the paper 2008ApJS..176...59B. In other words, if I do a text filter on the bibcode I get a single selection, and in the Object Types facet I see "GlCl ~".

It could well be correct, but I didn't see anything labelled as "GlCl ~" in the SIMBAD object reference page for the paper, but perhaps there's some "normalisation" going on somewhere, or I'm reading things wrong.
