resistics.time.reader_ats.TimeReaderATS(dataPath: str)[source]¶ Bases:
resistics.time.reader.TimeReaderData reader for ATS formatted data
For ATS files, header information is XML formatted. The end time in ATS header files is actually one sample past the time of the last sample. The dataReader handles this and gives an end time corresponding to the actual time of the last sample.
Notes
The raw data units for ATS data are in counts. To get data in field units, ATS data is first multipled by the least significat bit (lsb) defined in the header files,
data = data * leastSignificantBit,
giving data in mV. The lsb includes the gain removal, so no separate gain removal needs to be performed.
For electrical channels, there is additional step of dividing by the electrode spacing, which is provided in metres. The extra factor of a 1000 is to convert this to km to give mV/km for electric channels
data = (1000 * data)/electrodeSpacing
Finally, to get magnetic channels in nT, the magnetic channels need to be calibrated.
