Echo power spectrum
Bistatic DSS-14/RT-32 continuous wave echo power spectra of 2014 JO25 obtained at Zelenchukskaya, Badary and Svetloe observatories on April 18, 2017 from 10:58 to 11:13 UT. Solid and dashed lines denote echo power in the opposite circular (OC) and same circular (SC) polarizations as that of the transmitted wave.
