Notes. Absolute positions are accurate to better than 1 mas in each coordinate. θsep and PA are angular separations and position angles east of north of the background sources relative to OH 231.8+4.2 in Columns 4 and 5. Peak intensities in Columns 6 and 7 were obtained in our calibrator survey. Dashes indicate a non-detection.
