program in Python to automatic filter data and plot spectrograms.
HF-mag will be setup and tested at the geomagnetic observatory in Brorfelde.
field are normally measured at 1 Hz to follow the low frequent changes in the
field from daily variations to decades of years. Fluxgate magnetometers are
normally used for this. But for other purposes it is interesting to measure at
higher frequencies to find Schumann resonances or other fenomenances up to 40
Hz, and we are interested in this.
For this project we
have a fast and sensitive double scalar magnetometer (MFAM from
