Stellar Notes
UMa stream.
BAC and Heis (Argelander) differ on the correspondence between Flamsteed numbers and Bayer letters. The Heis convention | is adopted here. The corresponding interpretations are as follows: HR, FL, Heis, BAC; 3464, 46, -, Sigma1; | 3519, 51, Sigma1, -; 3532, 57, -, Sigma2; 3555, 59, Sigma2, -; 3563, 61, -, Sigma3; | 3575, 64, Sigma3, -. In the Bayer atlas (1603) the letter Sigma is in a position between these two groups | (BAC being south of Heis configurations) and could apply just as well to either. Most older catalogues give the BAC | convention.
