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

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];
opt = setMechTF(opt, 'IX', zpk([], par.w * dampRes, 1 / par.mass));
