| 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. | Hrt201 |
