1 Otero, Sebastian Alberto ASAS-SN magnitudes contaminated by nearby stars. Range has been corrected.
2 Schmeer, Patrick VSP Note: 19.3 mag. star 2.5" to the W.
3 Schmeer, Patrick U Geminorum type; maximum 1963 Sept. 10-15, mag. ~15.0 p (1964AN....288...49H). Quiescent spectrum shows moderate Balmer and numerous weak He I emission lines onto a slightly reddish continuum. However, no absorption feature for the red star is definitely detected (1999ApJS..122..243L).
