| + | Unclipped and un-baselined timeseries data. Seems to be only minor red-noise effects. Large bursts should be clipped:\\ | ||

| + | |||
| + | To test if red-noise is having a big influence on the power in the timeseries, performed FFTs of both the un-baselined data and baselined data. As can be seen there is only a moderate red-noise component in file0:\\ | ||
