7.3.5.2 Region Panel: stats

The second vertical tab, ’stats’, displays the statistics of each region. When more than a single region is drawn, one can select them one by one and the region panel updates image information and value statistics for each region. The informational section contains the frequency, velocity, stokes and brightness unit of the image. The beam area is also calculated from the header information of the image. The statistical properties of the pixels within in the region comprises the number of pixels (Npts), the Sum, Mean, RMS, Minimum, and Maximum of the pixel values, as well as the image flux integrated over the region. All values are updated on the fly when the region is dragged across the image.

Note that double-clicking the region will output the statistics to the terminal as explained above. This is an easy way to copy and paste the statistical data to a program outside of CASA for further use.
