We have divided the PNe with known individual distances into two categories according to the accuracy of the distances: the first category of distances is accurate up to 50% or less; we estimate the accuracy of the second category of distances to be within 50-150%. We would like to point out that the individual values given in the following table need not be wholly independent of each other, but we give them again in order to show the scatter of distances which is not small at all for some objects. However the present situation is much better than that some years ago because now almost 10% of all planetaries have known individual distances (77 in the first and 63 in the second category).
