Notes

Detected as an X-ray source (Revnivtsev et al., 2003). Possible symbiotic nature was suggested based on the IR spectra of the potential counterpart (Nespoli et al., 2008, 2010). In SIMBAD (Wenger et al., 2000), this target is referred to as [KRL2007b] 194 but points to different coordinates.
