Notes

In the first arXiv version of the paper by Saeedi & Sasaki (2022), the star was initially considered as a symbiotic star candidate. However, it was later reclassified as a possible QLMXB. Additionally, there was a suggestion that this star is an eclipsing binary with a period of 0.96 days, as mentioned in Martínez-vázquez et al. (2016).
