I started to test the Magneticfield Measurements for the power outage
I checked the status of the Magnetic field measurements.
The directory of Feb.20 had been generated, but it was empty, somehow.
I started the job and confirmed the data is generated.
I checked the magnetic field data today. A 1/f noise is found in both X & Y direction, larger than tha outside.
I susupect a noise from the DAQ and the portable powersurpply, and moved them as far as possible.
The 1/f noise amplitude was not changed. So it may be an environmental one.
