What is the difference between "bandwidth (KiB/sec)" and "Bw:...mean"?

      READ status:

            KiB IO, bandwidth (KiB/sec), runtime (msec)

            Submission latency: min, max, mean, deviation

            Completion latency: min, max, mean, deviation

            Bw: min, max, aggregate percentage of total, mean, deviation

What is the difference between "bandwidth (KiB/sec)" and "Bw:...mean"?

RD bandwidth (KiB/sec)  mean         WR bandwidth (KiB/sec)    mean
