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
