<h2>CLUSTER EFW Electric Field in GSE</h2>
<br/>
<br/> 
   <b>Electric Field in GSE</b> is obtained from
    <a href="http://caa.estec.esa.int/caa/" TARGET=_BLANK>CAA</a> C[1-4]_CP_EFW_L3_E3D_GSE <br/>
   <b>Note that Pi has not validated this product</b>.<br/>
    This dataset contains the  electric field in the inertial frame (i.e., vxB removed) in the GSE coordinate system, 
    using EFW electric field data from file C[1-4]_CP_EFW_L3_E and interpolated FGM magnetic field data from  
    C[1-4]_CP_FGM_5VPS products. The spin-axis component of the electric field is calculated with assumption of E.B equals 0 and with use of 2 electric field  
    components in the spin plane and three magnetic field components.
