SigMT is a python package designed for the processing of the raw magnetotelluric (MT) data to obtain the MT impedance and tipper estimates. It works in an automated way, so that manual time series inspection and editing are not required. Mahalanobis based data selection tool is implemented in the package to avoid the manual editing of time series. The final impedance estimation is done using the robust estimation method. Different data selection tools such as coherency threshold, polarization direction are included in this package.
