• B-Mag and V-mag for galaxies are now taken from LEDA instead of SIMBAD. Many magnitudes from SIMBAD claimed poor precision ("E" class from "A" - best to "E" - worst), while LEDA magnitudes usually show smaller errors. As usual, where it was decided to maintain SIMBAD values this is annotated in OpenNGC notes column. This also allowed to populate V-Mag column for over a thousand objects more.
• Some objects which are claimed as GPair or GGroup in NED had their classification corrected. Usually these are galaxies with a superposed star which led to a wrong classification. There were also a couple of misidentified galaxies which are double or triple stars.
• Finally, the remaining galaxies which haven't got any diameter or position angle available from LEDA or SIMBAD have been measured from DSS images and I put some rough estimated value myself.
