NoiseTAI

Documentation for NoiseTAI.

Overview

NoiseTAI generates synthetic random vibration time series with a prescribed acceleration Power Spectral Density (PSD), for use in Trapped Atom Interferometer (TAI) noise simulations.

The primary workflow is:

1. Load a measured or analytically defined target PSD from a two-column ASCII file via PSDData.
2. Generate a matching random waveform by superimposing M random sinusoids with physically derived amplitudes Aₖ = √(2·S(fₖ)·Δf/M) via AccelerationTrace, optionally rescaled to a desired target RMS acceleration.
3. Write time-trace and spectrum files for use in physics simulations via write_acceleration_trace and write_acceleration_spectrum.
