<H1>Use case: Galactic Star Content Simulator </H1>
<H2>Description</H2>
offer a service which supplies a realistic distribution of the Galactic stellar content in a given sky field. 

Could be used in [[VirtualTelescopeConfiguration][Virtual Telescopes]]; could be combined with other simulators (e.g. galaxy cluster simulators, Kuiper belt simulators, etc.) 

Once the service is located in a registry, and the description fits the user requirements, the user must be able to supply input parameters (limiting magnitudes, field positions, ...) and then get back observational parameters of a Galactic stellar distribution which can be combined with the output of other simulator(s) and input in e.g. an instrument simulator.

   1. definition of observation parameters (photometric bands, ...)
   1. search Galactic star simulator in a !Registry 
   1. check the availability of chosen observational parameters
   1. if yes query the Galactic star simulator for given field(s)
   1. possibly get simulation from fore-/background simulator(s)
   1. combine the simulations and input the result in an instrument simulator or image generator
