Notes. Photometry, spectral types, and reddening E(B − V) were determined from 2018 MUSE data. The error on the MUSE photometry is about 0.2−0.4 mag. Gaia EDR3 geometric and photogeometric distances and their uncertainties (i.e., the lower “l” and higher “h” values) are from Bailer-Jones et al. (2021).

^(a)

Listed only for sources with parallax error < 20%.

^(b)

HR Car.

^(c)

SIMBAD source GSC 08612–01828, but misidentified with star #34 in van Genderen et al. (1991).

^(d)

Foreground star, based on the spectral energy distribution.
