<h2>IMA Ion Moments</h2>
IMA ion moments are calculated in IRAP using Andrei Fedorov procedure.
<br/><b>Caveats</b>
<ul>
<li>
Density quality flag values :
<ul>
<li> 0.0 - 0.6 : Poor
<li> 0.6 - 0.8 : Acceptable
<li> 0.8 - 0.9 : Good
<li> 0.9 - 1.0 : Excellent
</ul>
VEX IMA protons and heavy ions number density could be considered reliable only in the case when corresponding quality flag
(<b><i>moments_quality_factor</i></b>) is greater than 0.6 and density values themselves are greater than 0.01 cm-3<br/>
It is highly recommended to download quality flag along with IMA ion densities.
<li><i>scan_flag</i> defines if there is scanning over elevation angles (scan_flag = 1) or not (scan_flag = 0)
</ul>
