<h2> Southern And Northern SKR phase systems at AMDA </h2>
<br/>
<br/> <UL>
  <li> Southern and northern SKR phase systems are taken from <a href="http://lesia.obspm.fr/kronos/skr_periodicity.php?page=1" TARGET=_BLANK>Observatory of Paris/LESIA website</a> <br/>
  
  <li> For each kronian hemisphere (North and South), we have:
    <UL>
	<li>
	  <b>period</b> : SKR dominant period in hours
	<li>
	  <b>phi</b> : SKR phase system (in which SKR maxima peak about 0deg)
	<li>
	  <b>drift</b>: SKR peak phase with respect to an arbitrary period (10.7928h in S and 10.6h in N)
    </UL>
  <li> The North data starts at day 2005-03-25.
