Notes. A machine-readable version of the full table is available at the CDS. A few rows of the table are given as an example. (1) Semimajor axis. (2) Ellipse-averaged r-band surface brightness. (3) Ellipticity defined as ɛ = 1−b/a with b semiminor axis. (4) Major-axis position angle measured north through east.
