Description

Echo power spectrum obtained on 2019-9-9 smoothed to a frequency resolution of 0.5 Hz. Power in the opposite circular (OC) polarization as transmitted is the solid line while the power in the same circular (SC) polarization as transmitted is the dashed line. The polariation ratio on this date was 0.34.

Observation Date: 2019-09-09 (05:51:22-07:02:38)

Resolution: 0.5 Hz

Polarization Ratio: 0.34

Download Options:

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.
