Generally, this is an uninteresting log. However, it may help on those rare occasions when a user notices data drop-outs and would like to determine if there was a diagnosed, real-time system problem.
An additional log containing system technical and performance information (as opposed to the "data" information, contained here) is also available.
An attempt has been made to faithfully reproduce the essentials of the data log. In some cases, abbreviations have been expanded and/or standardized. When specific computer processors are referenced, the name of the processor has been placed in double quotes.
Lines are used to bracket periods of continuous radar operation.
