IM Nor and 2U 1536-52
The proposed identification of IM Nor with 2U 1536-52 (as referred
in IAUC 7789) has proven to be false. 2U 1536-52 is an high-mass X-ray
binary QV Nor.
QV Nor = 1A 1540-53 = 3A 1538-522 = 1H 1538-522 = 2S 1538-522
= 2U 1536-52 = 3U 1538-52 = 4U 1538-52
The originally supposed identification of 2U 1536-52 with IM Nor
was already questioned by Wyckoff and Wehinger (1979) PASP 91, 173.
The optical candidate of this X-ray source was proposed by Cowley et al.
(1977) ApJ 218, 3L; Parkes et al. (1978) MNRAS 184, 73P.
