Notes

Initially classified as a symbiotic star in the GCVS according to Belczyński et al. (2000), possibly influenced by a suggestion in Bergner et al. (1995). However, later reclassification identified it as a high-mass X-ray binary with a B[e] donor (Clark et al. (1999)). Consequently, Belczyński et al., 2000 removed it from the list of known symbiotic stars.
