She calls Gamma Librae Zuben Elakrab.
Sigma Librae isn't anything on her list,
but there's another name for it: Zubenalgubi.
The Alcyone.de star database also has it as Brachium and Cornu, and
SolarFire 5 places it at 20 Scorpio 46.
I've entered Sigma Librae in my SF5 star menus as Zubenalgubi using
the Alcyone data (epoch 2000).
