| HJ 1628 | GYL 50. Goyal identified his pair as BD+31@4102, but his epoch-1900 | Gyl1966 |
| coordinates precess to the location of BD+32@4102. No 16" pair is | ||
| found in the vicinity of BD+31@4102, and AC2000 notes no "plate flaws" | WFC1998 | |
| mistaken for stars on the Potsdam plates used to generate Goyal's | ||
| measure. His value of theta may be reconciled with the position angle | ||
| of HJ 1628 by assuming he swapped the dx and dy measures between the | ||
| two Potsdam coordinates. |
