+  <p>Based on the requirement that all results produced by the LTP Data Analysis software must be
+	easily reproducible as well as fully traceable, the idea of implementing analysis objects (AO) as
+	they are described in S2-AEI-TN-3037 arose.</p>
+
+  <p>An analysis object contains all information necessary to be able to reproduce a given result. For 
+	example
+	<ul>
+ 		<li>which raw data was involved (date, channel, time segment, time of retrieval if data can be 
+	        changed later by new downlinks)</li>
+  	    <li>all operations performed on the data</li>
+		<li>the above for all channels of a multi-channel plot</li>
+	</ul>		
+  </p>
+  <p>The AO will therefore hold
+	<ul>
+ 		<li>the numerical data belonging to the result</li>
+		<li>the full processing history needed to reproduce the numerical result</li>
+	</ul>
+  </p>
+
+  <p>The majority of algorithms in the LTPDA Toolbox will operate on AOs only (these are always	methods 
+  of the AO class) but there are also utility functions which do not take AOs as inputs, as well as methods
+  of other classes. Functions in the toolbox are designed to be as simple and elementary as 
+	possible. </p>
