qaa Averaged Image Q/A Statistics

For the resampled images (detrended velocity, velocity, modulation, and intensity), the QA parameters are spatial averages of the images. The average is computed using a circular region centered on the Solar disk.

For the detrended velocity images (before registration, filtering, and resampling), the QA parameters are the spatial averages and the north-south and east-west gradients.

Bad output images are not included in the AVER QA statistics.
