Dear Willy et al, My suspicions ares confirmed...
I have just received a message from David Leafe: Unfortunately, although I sent them the revised scientific information as we agreed it, they had to cut it down and I'm not sure that it now all makes sense... The errors are NOT the fault of David Leafe!! Moral number 2: we must always be careful when trying to identify sources of errors! Very best wishes Frank --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
