 radiation is emitted from the observer's location.
   The terminology was retained for consistency with earlier
   documentation.
 
   Below, we indicate the aberration corrections to use for some 
   common applications: 
 
      1) Find the apparent direction of a target. This is 
         the most common case for a remote-sensing observation.
 
            Use &quot;LT+S&quot; or &quot;CN+S&quot;: apply both light time and stellar
            aberration corrections.
 
         Note that using light time
