1The sum of all observations may be lower, because double observation in ITF are not uncommon.

2Satellites, Rover and Radar observations means, that these are a part of all observations in the left column, not additional.

3The sum of all stations is lower, because stations take part in several files.

4The sum of all objects is far much too high, many of the ITF objects are multipel or will be identified with other objects in future.
