discov_num notes refcode
CHE 9 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 dx, which should be +0'.0708. Chevalier applied
his declination offset from the plate center in the wrong direction,
leading to an error of over 25' in the coordinates. The image for the
pair at the corrected coordinates is elongated on the Aladin image;
due to uncertain relative proper motion it's impossible to tell
whether his rho and theta values are correct. Hrt2012b
