Comparison of fwhmwhisker from different methods

I compared the fwhm and whisker length from different methods (including the Quick Reduce and Image Health) based on the images taken during the 11/24-11/25 night. The results are show in the following plots. In all the plots, I used the weighted moments with a weight kernel size of 2 pix as fiducial values (x axis) and plot the other measurements as y axis marked with different symbols. As you can see, the IH and QR return smaller values.
