| thresh_rel | float | `0.1` | Minimum relative difference between two values to consider the latter as a break candidate. See condition (1) |
| thresh_abs | float | `0.01` | Minimum absolute difference between two values to consider the latter as a break candidate. See condition (2) |
| first_der_factor | float | `10` | Multiplication factor for arithmetic mean of the first derivatives surrounding a break candidate. See condition (3). |
| first_der_window | [offset string](docs/ParameterDescriptions.md#offset-strings) | `"12h"` | Window around a break candidate for which the arithmetic mean is calculated. See condition (3) |
| scnd_der_ratio_range | float | `0.05` | Range of the area, covering all the values of the second derivatives quotient, that are regarded "sufficiently close to 1" for signifying a break. See condition (5). |
| scnd_der_ratio_thresh | float | `10.0` | Threshold for the ratio of the second derivatives succeeding a break. See condition (5). |
| smooth | bool | `True` | Smooth the time series before differentiation using the Savitsky-Golay filter |
| smooth_window | [offset string](docs/ParameterDescriptions.md#offset-strings) | `None` | Size of the smoothing window of the Savitsky-Golay filter. The default value `None` results in a window of two times the sampling rate (i.e. three values) |
| smooth_poly_deg | integer | `2` | Degree of the polynomial used for smoothing with the Savitsky-Golay filter |
