@@ -11,7 +11,7 @@ highest spatial frequency preserved in the data. The latter is 1 cycle/km for th
 resolution of Marouf's reconstructed profiles. The value corresponds to ~750 m
 processing resolution as defined in MTR86. The bandwidth of the lowpass filter in the final stage of the data processing chain determines such frequency and is selected to achieve the desired resolution.
