Anomaly Detection: Time Alignment & Visualization

This workflow performs time alignment on different time series. It reads 6 of the original 28 data files containing amplitude values organized by time and frequency (FFT results); calculates average amplitudes for each frequency bin and date; performs time alignment; writes output to a CSV file AlignedData.csv; performs various visualizations.
