J/other/IBVS/4678   Haro-Chavira infrared stars identifications    (Skiff, 1999)

Identifications for the Haro-Chavira "infrared stars". Skiff B.A. <IAU Inform. Bull. Var. Stars, 4678, 1 (1999)> =1999IBVS.4678....1S
ADC_Keywords: Stars, variable Abstract: The first seven extremely-red Haro-Chavira stars were published by Johnson et al. (1965ApJ...142.1249J), which includes BVRIJHKLMN photometry for them. 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'. The finder charts were thus indispensable for positive identification on the sky. Two stars (HC 56 and HC 62) defeated my attempts to locate them. File Summary:
