Gvr201000138+7233 BUP 2 Misinterpretation of a note in Bu_1913 resulted in these three BUP components being associated with 00103+7231HJ 1941, when all three were actually measured relative to a planetary nebula (NGC 40) about 3m following the HJ pair. Since one BUP component was also the primary of the MLR 282 triple system, the BUP component designations were changed to become part of the MLR multiple.

We adopt the aperture photometry values for the differential photometry, and let the errors be represented by the scatter between PSF fitting results and the aperture photometry.

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.
