These figures are computed over Stelvia's catalogue —stars visible to the naked eye, down to magnitude 6—, not over the constellation's real total: the count, the brightest and the nearest all refer to that catalogue. The region of the sky comes from the median declination of its stars; the month, from their mean right ascension.
