I'm working on the offline analysis for the ER data, focusing on the 80-110Hz peaks. (See this plot in klog12341)

Here, I trace the peak frequencies for the first segment in this klog (start from GPS1260604820) : 

• plot1 : example of one ASD
• plot2 and plot3 : time series of the peak frequencies and median-subtructed them
• plot4 : ASD of plot2
