The table below shows the various aggregate metrics measured from MA to target comparing pinger.slac.stanford with pinger-raspberry.slac.stanford.edu. The columns are arranged in pairs. The first of each pair is for pingerr.slac.stanford.edu, the second for pinger-raspberry.slac.stanford.edu. Each pair is measured over the same time period. Different pairs are measured over different time periods.
The errors (+-) are estimated as follows:
- The Min RTT error is the IQR of the minimum RTTs from each set of pings for the time period.
- The Avg RTT error is the standard deviation of the average RTTs from each set of pings for the time period
- The Median RTT error is the IQR of all the individual RTTs from all sets of measurements for the time period
- The IQR IPD error is the IQR of the hourly IQRs for the time period
