Sudden ionospheric disturbance monitor with Stokes data product
This package is a VLF receiver for monitoring VLF transmitter signals for evidence of transients indicating ionospheric disturbances, usually caused by x-ray bursts from the sun. It takes sample pairs from dual-channel sound cards and spectrally processes them to Stokes parameters. Data are plotted as time series and in scatter plots.
Experimental technique based on the measurement of first-order reversal curves (FORCs) is typically used to evidence the intensity of interactions between the switching physical entities in ferromagnetic samples. It is important to mention that the distribution of coercivity can also be identified from a FORC diagram.
dFORC application represents a tool to compute the FORC distribution from the specific experimental data.
