Loading DataCube surveys

To access both 2D and 3D DataCube surveys data, open a left panel by clicking on a Search icon and enter galactic coordinates (see Fig. 3), for example glon:20,glat:0,rad:0.2.

Confirm a VLKB query by clicking on the Query button (see Fig. 3). Wait till query will be executed and the first available 2D data is loaded.

In the query results the 2D data is marked as “Continuum” surveys (see Fig. 4). The total number of all available surveys from the query is displayed at the botton. The user can navigate through pages to preview all surveys and adjust the number of surveys displeyed per page, that is 10 by default

Multi-tab interface for visualisation of 2D and 3D data

Similarly to 2D data, the datacubes for current VLKB query is available for selection from right panel. To visualise the 3D DataCube data, the user should click on selected survey in the query results. The DataCube data would be loaded in a separete web browser tab with available interaction in 2D and 3D views (see Fig. 5).
