Numbers obtained from S20 No Bias data

The following stats are obtained from all events selected by the NoBias stripping line. That's 5 million events of which 300k pass L0, 20k Hlt1 and 3k Hlt2. That's not enough to make Hlt2 correlations but has the advantage of allowing L0 and Hlt1 stats for the whole of 2012.
 

L0 statistics

First the fraction of events from the relevant lines in L0-accepted and stripping-accepted events is given. The ratio column gives the ratio of these numbers.
