Amplitude error statistics for the six techniques considered. MSTID (right column) and LSTID (left column) parameters correspond to the ones presented in Table 1; the ionospheric thin shell height was set to 350 km. The top panels show the CDFs of AME for the different techniques (each line corresponds to the CDF of a given technique). X-axis shows the AME error in TECu, while the Y-axis corresponds to the probability P(AME) of having an error equal to or smaller than the corresponding X value. The bottom panels, instead, present the median along with their related percentiles (5, 16, 84, and 95) for the different filtering/detrending techniques.
