In preparing our paper we have had several discussions with colleagues belonging to the ISOLDE Community to collect information, both formal like photos but also informal information about exciting experimental results. For us it was both a pleasure and a problem to select a few examples of the beautiful results our community have obtained over the years. One of us were 'on-line' at CERN already in 1972 when Ernst Otten and his, at that time young team, made the discovery of the strange behaviour of the lightest known Hg isotopes. This discovery did not only give fame to the group but was essential for the future of ISOLDE at CERN.
Figure 8. Left: present status of the systematics of mean-square radii 
for Hg isotopes measured at ISOLDE. Right: low-energy part of the 182Hg level scheme. The 
ground state is found to be weakly deformed and predominantly of oblate nature while the 
at an energy of 335 keV is more deformed.

It was obvious for both of us to include a comment about this as a prime example of the 'past'. With the very open scientific atmosphere at ISOLDE both of us were aware that new interesting Hg results were under analysis. By mistake a picture with part of the new preliminary results was included in our figure 8. There are no numbers given and our main purpose was to indicate that new data exist. To avoid any problem to the future publication of these interesting results, we have therefore revised our figure and shown instead the status of Hg charge radii at the time when our paper was published. We have also changed the figure caption accordingly and removed [70].
