LAU 4 BRT1344. Barton derived his measurement from a Toulouse plate observed Brt1935a
as part of the Astrographic Catalogue project. However, his secondary
was apparently either a plate flaw measured as a star, a reduction
error, or a typographical error in the preparation of the catalogue.
Thanks to John Nanson (2014, private comm.) for alerting us to this
missing measurement.
