a See McClintock & Remillard (2006; and references therein) for columns 3β5, Orosz (2003) for columns 6β7, plus additional references given below. b A prefix to a coordinate name is enclosed in parentheses. The presence/absence of a βJβ indicates that the epoch of the coordinates is J2000/B1950. c Year of initial X-ray outburst/total number of X-ray outbursts. d Period and f(M) corrections by AM Levine and D Lin, private communication. e Colon denotes uncertain value or range. f Additional outbursts in optical archives: A 0620 (1917) and V404 Cyg (1938, 1956). g Casares et al. 2004; possible alias period of 61.5 hr. h Orosz et al. 2004. i Estimated by Kong et al. 2002. j Hynes et al. 2003. k Period confirmed by A.M. Levine and D. Lin, private communication. l βQβ denotes quasi-persistent intervals (e.g., decades), rather than typical outburst.
