    88Logs and displays latency and outages of data from a specified ring (Windows only) 
    99== Details == 
    10 This program takes waveforms dropped in InRing and logs latency and outages of the data. Each time a trace arrives, its start time is compared to the end time of the last packet. When there is a gap the outage is logged to a data file for that station. Also, the start time is compared to real-time, and latency is determined. Whenever the latency changes, it is also logged with start and end time to the file. Latencies are grouped generally: <1' = 0; 1'-2' = 1; 2'-3' = 2; 3'-5' = 3; >5' = 4. Here, latency is described as present time minus mid-time of the packet.

    1212The graphical output shows a line for each station in the .sta file for a set length of time. Colors on the line represent the latency of the station over that time interval.
