---+ Description

This topic is dedicated to the ASPRO data model describing both the interferometer (stations, instruments, configuration) and an observation using an interferometer configuration with user parameters.


---++ Interferometer

The interferometer is spread in two parts : a description with all possible elements (stations, delay lines, pops, switchyard, instruments ...) and one or more configurations to limit the real possibilities with these elements (instruments with their baselines ...).

---+++ Interferometer description

The interferometer description has the following elements :
   * observatory position
   * list of Telescopes (diameter / adaptiveOptics)
   * list of Stations (relative Position / associated Telescope / fixed offset / horizon)
   * list of channels (useful ?)
   * list of delay lines (maximum throw)
   * switchyard (fixed delay per station - delay line couple) : TBC
   * pops (fixed delay per station - pop index couple) : TBC
   * list of instruments

TBC

---+++ Interferometer configurations

For now, the configurations are really useful to model the VLTI restrictions associated to an ESO Call for Proposal Period like the list of allowed baselines per instrument.

<br/>The other interferometer have only one configuration listing all possible baselines per instrument.

---++ Observation

The observation is defined an the observation setting with :
   * when : date
   * interferometer / instrument with the chosen stations 
   * list of targets
   * other parameters : TBC

---++ Data Model Xml Schema

The current data model is written as an Xml schema and is provided below :

   Current Version : 18 Nov. 2009 :

   * [[%ATTACHURL%/AsproOIModel.xsd][AsproOIModel.xsd]]: Xml schema for the data model


---+ Sample documents

The following documents illustrate two interferometer description for the VLTI and the CHARA interferometers :

   * [[%ATTACHURL%/VLTI.xml][VLTI.xml]]: VLTI description

   * [[%ATTACHURL%/CHARA.xml][CHARA.xml]]: CHARA description
