    452452<u>Latency:</u> Latency is defined in BNC by the following equation:
     
    460460</pre>
    461461<p>
    462  BNC can average the latencies per stream over a certain period of GPS time, the 'Performance logging' interval. Mean latencies are calculated from the individual latencies of at most one (first incoming) observation per second. Note that computing correct latencies requires the clock of the host computer to be properly synchronized.
    463 </p>
    464 <p>
    465 <u>Statistics:</u> BNC counts the number of GPS seconds covered by at least one observation. It also estimates an observation rate from all observations received throughout the first full 'Performance logging' interval. Based on this rate, BNC estimates the number of data gaps when appearing in subsequent intervals.
    466 </p>
    467 <p>
    468 Latencies and statistical information can be recorded in the Log file/section at the end of each 'Performance logging' interval. Select a 'Performance logging' interval to activate this function or select the empty option field if you do not want BNC to log latencies and statistical information.
