+This module is similar to the <link linkend="calc-apcoords">Apparent 
+Coordinates module</link>, but it only applies the effect of 
+<link linkend="ai-precession">precession</link>, not of nutation or 
+aberration.  
+</para>
+<para>
+To use the module, first enter the input coordinates and their epoch
+in the <guilabel>Original Coordinates</guilabel> section.  You must 
+also fill in the target epoch in the <guilabel>Precessed 
+Coordinates</guilabel> section.  Then, press the 
+<guibutton>Compute</guibutton> button, and the object's 
+coordinates, precessed to the target Epoch, are presented in the 
+<guilabel>Precessed Coordinates</guilabel> section.
