NGC 6406 is a double star at Bigourdan's place. He has four micrometric observations of it, so there is no doubt about the identification. He notes a nearby star of magnitude 12.2 at PA = 265 degrees, distance = 1.2 arcmin. The position angle is actually about 95 degrees. I suspect that Bigourdan's value ought to read 85 degrees.― NGC Notes by Harold Corwin
