Overview
</h2>
<p>
NDPluginStats computes the following.
</p>
<ol>
<li>Basic statistics: minimum, maximum, mean, sigma, total, and net (background subtracted).</li>
<li>Centroid and sigma values in the X and Y dimensions.</li>
<li>Profiles of the array in the X and Y dimensions. A total of 8 profiles are calculated:
<ul>
<li>The average profiles in the X and Y directions. </li>
<li>The average profiles in the X and Y directions, for array elements greater than
the centroid threshold.</li>
<li>The profiles in the X and Y directions at the X and Y centroid position.</li>
<li>The profiles in the X and Y directions at a user-defined X and Y cursor position.</li>
</ul>
</li>
<li>A histogram of the values (e.g. number of pixels versus intensity per pixel).</li>
</ol>
<p>
Each calculcation can independently enabled and disabled. Calculations 1 and 4 can
be perfomed on arrays of any dimension. Calculations 2 and 3 are restricted to 2-D
arrays.
</p>
<p>
Time-series arrays of the basic statistics, centroid and sigma statistics can also
be collected. This is very useful for on-the-fly data acquisition, where the NDStats
plugin computes the net or total counts in the detector or an ROI. It can also be
used to quickly plot a time-history of beam position or width, etc.</p>
<p>
NDPluginStats inherits from NDPluginDriver. The <a href="areaDetectorDoxygenHTML/class_n_d_plugin_stats.html">
NDPluginStats class documentation</a> describes this class in detail.
</p>
<p>
NDPluginStats.h defines the following parameters. It also implements all of the
standard plugin parameters from <a href="pluginDoc.html#NDPluginDriver">NDPluginDriver</a>.
The EPICS database NDStats.template provide access to these parameters, listed in
the following table. Note that to reduce the width of this table the parameter index
variable names have been split into 2 lines, but these are just a single name, for
example <code>NDPluginStatsComputeStatistics</code>.

If the values of CentroidThreshold, CursorX, or CursorY are changed then the centroid
and profile calculations are performed again immediately on the last array collected.
Thus updated centroid statistics and profiles can be displayed even when new arrays
are not being acquired. These calculations are only performed when enabled by ComputeCentroid
and ComputeProfiles.</p>
