CHE 4 Chevalier's measure was correct, but his published (dx,dy) predict Che1908
different (rho,theta) than published. This was apparently due to a
typographic error in dy, which was printed as -0'.0317 rather than
-0'.0617. There is also an apparent trigonometric error in his value
for position angle. Chevalier gives a value for theta of 154.62 deg,
but all later measures in the WDS give values of about 204.0 deg. It
appears his value should be 360-154.62 = 205.38 deg instead. Hrt2012b
