measurement (say from outgassing or radon) the ROI can be used to select only good data (all graphs
will update with only data from the selected time period). All of these graphs should be reviewed to
ensure that the measurement was successful.

Analysis
Watch Data: If desired, the Analysis Panel can be opened while a measurement is in progress. More
complete details are presented in the
section. Here we only wish to suggest how the
information displayed can be useful for determining whether or not a measurement is proceeding well.
For instance, the main graph, Anode Energy vs. Risetime, can show if there are issues with outgassing
(see
). Further, the rates of various event types (e.g. ceilings and rounds) should stay relatively
constant from run-to-run. Excessive numbers of any kind of events can indicate a problem. Scrolling
through some traces can show any abnormal noise that may have cropped up (such as vibration from
unusual environmental activity). While the majority of runs will show no problems, spending a few
minutes looking through the data can alert the user to potential issues early, before a day has been
wasted taking bad data.
e)
Run reporting
Exporting Files: After the run is over and the results have been checked thoroughly, the user will
typically want to generate a report. This can be as simple as inserting the reported emissivity into a
spreadsheet, or as complicated as running custom pulse-shape analyses. CounterMeasure facilitates
reporting by having several different files available for export, most notably a full measurement report,
as discussed in
. This export can be performed either immediately after a run ends,
or later, after reanalyzing a file.
