actually that's the way I use them. I have some data from different
sources (not many data though, just what I need). In order to check them
and to solve and correct some inconsistencies I have found, I have used
the TK50 data published on the top50 CD (actually for North
Rhine-Westphalia).

Markus, I strongly agree with you about this policy. However, the top50
CD was a cheap way for the issues I had to solve (see above)

Regards,

Carsten
