${}^a$ See McClintock & Remillard (2006; and references therein) for columns 3–5, Orosz (2003) for columns 6–7, plus additional references given below.
${}^b$ A prefix to a coordinate name is enclosed in parentheses. The presence/absence of a “J” 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.
${}^l$ “Q” denotes quasi-persistent intervals (e.g., decades), rather than typical outburst.
