Haro-Chavira infrared stars identifications

The positions listed for these stars are consistently nearly a full degree in error, as a consequence of which they seem to have been overlooked in later literature. The offsets are parallel to the direction of precession, and the error evidently arises from the application of 100 years of precession motion with the wrong sign.

These stars were unambiguously identified using the published charts, which are copied from the POSS-I prints of the region. In a follow-up work, Chavira (1967BOTT....4..197C) published a more extensive list of stars based on far-red objective-prism and direct plates. The main difficulty in the identifications was the poor positions, some in error by 10'.
