Notes. (2): Identification number from the Strasbourg Catalog of PNe; (3): integrated V-band intensity of central star; (4): spectral classification of central star ([WC11]: Wolf-Rayet type; WELS: weak emission line star, normal chemical composition); (5): spectral classification of binary companion (A-type companions dominate the spectrum, spectral type of CSPN unknown); (6): basic morphology of the planetary nebula, R (round), E (elliptical), B (bipolar); (7): X-ray classification, N (non-detection), SP (soft point source), HP (hard point source), D (diffuse source), F (future Chandra target);
