Search and display data around a Titan fly-by with VESPA
For this use case, we use 3DView and another tool called TopCat to display data searched by 3DView among VESPA services. We want to search for data provided by VESPA around a Titan flyby by the CASSINI spacecraft
The Titan fly by is described below (source PDS):
Start 3Dview : goto http://3dview.cdpp.eu and click on the Launch 3DView button, save the file as launch3dview.jnlp and run the application
In the desktop bar, select File/New to open a new 3D scene
With the File/Manage scene menu,create a scene with Titan as central body, CASSINI as spacecraft and TIIS as coordinate system from 2016-02-16T21:00:00 to 2016-02-17T03:00:00
Select the VESPA option in the Science Menu
This opens the VESPA pop-up window,with Target,StartTime and StopTime already selected from the scene.
Launch the animation and stop it at about 23:16,and click on the Select Region button to add a new search keyword.
click on the Select Region button to add a new search keyword. The following pop-up window is opened.
Then select a region
To increase the number of possible responses, change the start date to 2010-02-16T21:00:00 and click on Search
The list of services is displayed in the left part of the window. The name of each service is displayed with the corresponding number of results.
Click on titan to display the results of this database.
Launch TopCat. This will automatically start the SAMP HUB hosted by TopCat.Right click on a raw displays several options depending on the data format.Select send via SAMP to TopCat. This option is available for data of mime type equal to application/x-votable+xml only.
The table is loaded by TopCat, and visible in the Table List after a few seconds. Open the plane plotting window to display the contents of the table.
In the plane plot window, Select temperature on X-axis and altitude on Y-axis.
