= Lentickle model for C1 =
Scripts are found in iscmodeling/LentickleC1

== Purpose ==
 * To get the OLTs
 * To get noise budget
 * Sensing matrix with loops

== Main script to execute ==
C1lentickle.m builds the Optickle model, then inclides the loops defined by C1cucumber.m
The Optickle model for C1 is same as Kiwamu's scripts, optC1:
 * optC1.m ... Optickle model
 * paramC1DRMI.m ... physical parameters for optC1
 * probesC1_00.m ... probes of the model

== C1cucumber setting ==

[[attachment:filters.png|bodeplot of the filters]] These filters already have pendulum compensation. Therefore in cucumber, you don't need the pendulum compensation (mirrFilt) matrix. Here we use a flat (unity) mirrFilt.


* Mechanical transfer function
dampRes = [-0.1 + 1i, -0.1 - 1i]; <<BR>>
opt = setMechTF(opt, 'IX', zpk([], par.w * dampRes, 1 / par.mass)); <<BR>>

 * '''Quantum Noise Estimation''' (correctness unknown)

- both open loop and closed loop

- full lines are adding all contributions from all sensors (weighted by their TF to that DOF)

- dashed lines are only contribution from sensor corresponding to that DOF

- in open loop, full line and dash overlap as expected
