             abstract = "The study of the properties and variations of planetary boundaries 
                         such as magnetosheaths and bow shocks is an important subject for 
                         magnetospheric dynamics and interaction with solar wind. The 
                         identification of these boundaries is important for those studies. 
                         Thus, the Haar wavelet decomposition technique is used to detect 
                         the planetary magnetosphere boundaries and discontinuities. We use 
                         the magnetometer data from the CASSINI and MESSENGER spacecraft to 
                         identify the abrupt changes in the magnetic field when the 
                         spacecraft crossed the magnetospheric bow shocks and magnetopauses 
                         of Saturn and Mercury, respectively. The methodology based on 
                         variance obtained by scale and edge identifications was shown to 
                         be a simple tool to perform this task. The results confirm that 
                         the Haar transform can efficiently identify the planetary 
                         magnetosphere boundaries characterized by the abrupt magnetic 
                         field changes. Due to this wavelet function to be a discrete 
                         function it promotes the abrupt and sharp identification of the 
                         boundaries. It is suggested that this technique can be applied to 
                         detect the planetary boundaries as well as the discontinuities 
                         such as the shock waves in the interplanetary space.",
