Fit of filter cavity bandwidth

After using the correct Airy function, we can get a better fit of our filter cavity. It gives us the results as below.

velocity bandwith
200Hz/s 119Hz
400Hz/s 114Hz
80Hz/s 115Hz

According to this result, we can say our filter cavity's Bandwidth(for infrared) is 116 +/- 2.16Hz.

I put some other parameters of fitting here.

velocity bandwith r1(r2 is assumed as 1) Finesse
200Hz/s 119Hz 0.999251 4190
400Hz/s 114Hz 0.999279 4355
80Hz/s 115Hz 0.999272 4311

r1=0.9992673 +/- 1.19e-5

Finesse=4285.3 +/- 69.7
