Dear all,
i downloaded a rosbag from the internet and looked at the info of this file:

topics: tf 152840 msgs @ 99.2 Hz : tf/tfMessage
As you can see, the topic __tf__ have 152840 messages and after that there is the number 99.2 Hz.
I computed:
(end_time - start_time) / number of messages
and i got ca. 70 Hz.
What is the meaning of the number 99.2 Hz?
