                         present in the plasma oscillations in the Martian magnetosheath. 
                         We have selected magnetosheath crossings and applied the Morlet 
                         wavelet transform to the electron density and temperature data, 
                         obtained from the Analyzer of Space Plasmas and Energetic Atoms 
                         experiment (ASPERA-3), onboard the Mars Express (MEX). In a study 
                         of 9667 magnetosheath crossings observed from 2005 to 2016, we 
                         have found 22,912 frequencies with high wave power between 5 and 
                         60 mHz for the electron density data, For about 2/3 of the high 
                         wave power periods (63.3%), the most energetic frequencies were 
                         identified in the range 520 mHz. The analysis of the electron 
                         temperature data led to similar results, with 61.9% of the highest 
                         power frequencies in the 520 mHz range. No significant influence 
                         of the solar cycle on the frequencies of ULF waves has been 
                         observed in our analysis. The frequencies obtained here are near 
                         the O+ gyrofrequency. The main fact that controls the ion 
                         gyroradius is the interplanetary magnetic field that is compressed 
                         around the planet.",
