 # finesse simulation O4
 
+This simulation aims to replicate simulation result from
+[Optickle](https://git.ligo.org/virgo/virgoapp/simulinkNoiseBudget/-/blob/master/DRITF/scatterRadiationPressure.m)
+to get transfer functions between sensitivity and benches movement.
+
+The final objective is to use [Finesse](https://finesse.ifosim.org) to compute
+future backscatter noise projection.
