Test use case following AstroGrid format with some small changes.
<H1>Use case: interpreting structure of X-Ray clusters</H1>
<H2>Description</H2>
A user has obtained and analysed a detailed X-Ray image of a galaxy cluster 
(see for example Schuecker _et al_, 2004) showing small scale
sub-structure. To investigate whether the interpretation in terms
of turbulence is realistic a similar analysis on simulated images is desired. This requires availability of hydro simulations of galaxy clusters with the appropriate physics included and services that can create mock images from this simulation.

<H2>End result:</H2>
Mock images are obtained from simulated galaxy cluster 
ready for comparison to real X-Ray observations.

<H2>Flow of events</H2>
   1 User browses registry for appropriate virtual telescope service based on simulation and service meta-data
   2 Selects service and provides input 
   3 Service executes and provides (links to) results
