<h2>MEX IMA proton solar wind proxy</h2>
Mex IMA protons density and velocity in SW is a subset of IMA ion moments dataset on applying an orbital restrictions.
IMA ion moments are calculated in IRAP using Andrei Fedorov procedure.
<br/><b>Caveats</b>
<ul>
<li>IMA/MEX operates in two modes -16 / 2 elevation angles (averaged). In <i>2 elevations</i> mode the quailty flag value is undefined (== 0).
Normally the quality of IMA measurements in SW is good enough.
Density quality flag values :
<ul>
<li> 0.0 : Undefined (2 elevation angles mode)
<li> 0.0 - 0.6 : Poor
<li> 0.6 - 0.8 : Acceptable
<li> 0.8 - 1.0 : Good
</ul>
<li>Due to instrument limitations IMA/MEX measures protons with the energies higher than 1 keV. If possible
the proton parameters are reconsructed from the <a target='new' href="help/auto/img/mex_ima.png">ghost' distrubution function.</a>
<br/> To compare : MAVEN/SWIA - MEX/IMA for 90 episodes in SW when the distance between s/c is less than 1 Rm :
