Figure S1. Reproduction test of Figure 1 and Figure 3 in I&U16 using
the same satellite-central station pair as theirs. The central station
is Kitaibaraki (0214), the satellite is PRN26. The regression curves are
septic functions. (a) The day of Tohoku-Oki earthquake. The time of the
mainshock is indicated by the vertical line. (b) Forty days (DOY30), (c)
30 days (DOY40), (d) 20 days (DOY50), and (e) 10 days (DOY60) before the
earthquake. They are good reproductions of I&U16. |
