CSV file is the raw data corresponding to the viewed cw spectra. The CSV file consists of three columns. The first column is the doppler frequency (Hz), the second column is the echo power in the same sense (SC) and the third column is the echo power in the opposite sense (OC). Echo power is in units of standard deviation above the noise baseline.
