I'm confused by these inverse units. Is 1fb^-1 = 1000 pb^-1?

Yes, 1 fb^-1 is 1000 pb^-1, and 2 pb^-1 is double the statistic data of a 1 pb^-1 dataset.

To add some more information: All the electronic components of the experiment have implemented a counter which basically counts the number of these buckets that have passed the experiment. This information is send out with the measured data by the electronics upon a trigger (command to read out the ...
