Gts.detrend

class pyacs.gts.Gts.Gts(code=None, lat=None, lon=None, h=None, X0=None, Y0=None, Z0=None, t0=None, data=None, data_xyz=None, data_corr_neu=None, data_corr_xyz=None, offsets_dates=[], offsets_values=None, outliers=[], annual=None, semi_annual=None, velocity=None, ifile=None, log=None, metadata=None)[source]
detrend(method='L2', periods=[], exclude_periods=[], log_dir=None)

Detrend time series and store velocity (and optional offsets) in attributes.

Parameters:

  • method (str, optional) – Estimation method (e.g. ‘L2’). Default is ‘L2’.

  • periods (list, optional) – Periods used for velocity estimate. Default is [].

  • exclude_periods (list, optional) – Periods excluded from velocity estimate. Default is [].

  • log_dir (str, optional) – Directory for Gts-specific log file {self.code}.log. Default is None.

Returns:

Detrended time series (velocity attribute set).

Return type:

Gts

Notes

Outliers in Gts.outliers are omitted; offsets in Gts.offsets_dates are estimated simultaneously.
