9	Original (fixed weights)	35(1-(FWHM-4.7)/5.4) + 5(1-(Eccentricity-0.33)/0.45) + 10*(SNRWeight-0.93)/1.02 + 50
10	Original (variable weights)	51(1-(FWHM-4.7)/5.4) + 8(1-(Eccentricity-0.33)/0.45) + 21*(SNRWeight-0.93)/1.02 + 20
11	Aggressive FWHM	51((1/(FWHM^2))-0.00980296049406921)/0.0354663921541879 + 8(1-(Eccentricity-0.33)/0.45) + 21*(SNRWeight-0.93)/1.02 + 20

13	Notes
14	- Enter the minimum and maximum values calculated by SubframeSelector for each of the metrics (blue boxes)
15	- Adjust the weights to your preference
16	- The range sets how much variance in the final weighted calculation. If set to 100, then the output weights will range from 0 to 100, meaning the worst frame would have no contribution to the final stack.
17	- I like to use a range of 40 to 60, but it's up to you
18	- If you want to weight based more on FWHM, I would use the last expression since the 1/FWHM^2 function will cause a more rapid drop off of weights as the FWHM increases
19	- Once you've entered the data copy the expression to your SubframeSelector Weighting expression field (there may be spaces at the end of the text that will need to be deleted)
