| RPCa | CPCa | Absolute Difference | |
|---|---|---|---|
| Average velocity at zenith (cm/s) | 6.5 ± 0.1 | 6.4 ± 1.2 | 0.1 |
| Average velocity at nadir (cm/s) | 1.8 ± 0.7 | 2.0 ± 1.1 | 0.2 |
| Peak velocity at zenith (cm/s) | 11.5 ± 0.6 | 10.2 ± 0.9 | 1.3 |
| Peak velocity at nadir (cm/s) | 4.3 ± 0.4 | 5.0 ± 0.6 | 0.7 |
| Average | 0.6 ± 0.6 |
a Mean values ± SDs.
