GraFIT: Frequency response function identification in Gravitational Wave detectors
GraFIT identifies frequency-response functions (FRFs) measurements for gravitational wave detectors. The toolbox uses a local modeling method to estimate FRFs to reduce the impact of transient effects. The code handles systems of arbitrary input and output dimensions and supports closed-loop operation. GraFIT is fast, inexpensive, and accurate, and provides both Python and MATLAB implementations.
