Notes. (#)Reported as a likely RCB star based on a brightness drop observed by the ASAS-SN survey (Jayasinghe et al. 2017) and being flagged in Tisserand (2012) due to its IR colours characteristic. (##)A decline of ∼1.6 mag at JD∼2458000 days was observed by the monitoring survey ASAS-SN (Jayasinghe et al. 2018). ( ⋆ )Named GDS_J1613117-503040 in the Bochum survey. ( ⋆ ⋆)Also known as KDM 5651 : previously known candidate RCB (Morgan et al. 2003) as reported by Stefan Hümmerich (light curve available on AAVSO variable star website). (r1)Also known as the variable star AC Ser. (r2)Listed as candidate RCB GLIMPSE-RCB-Cand-1 in Tisserand et al. (2011). (r3)Listed as candidate RCB GLIMPSE-RCB-Cand-2 in Tisserand et al. (2011). (r4)Also known as [MH95] 580, and Gaia 16aau, a Gaia Alert ATEL http://www.astronomerstelegram.org/?read=8681. (r5)Also known as RAW 658 in the SMC carbon stars catalogue from Rebeirot et al. (1993). (r6)Also known as MSX-LMC-1795 (Matsuura et al. 2014) and OGLE-LMC-RCB-21 (Soszyński et al. 2009). (r7)Also known as HV 12862 and KDM 6829. (r8)Also known as the variable star IZ Sgr. It was surprisingly classified as a Mira type star (M6 spectral type) by Houk (1967) after a spectroscopic follow-up. (M)Variations observed by Gabriel Murawski (priv. comm., 2019), light curves available on AAVSO variable star website.
