Corwin's Notes
=====
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.
