=VAO time series demo=

The purpose of this demo is show how the VO enables time domain science via interoperability between data provider and analysis services.

(1) We start at the [|VAO Data Discovery Tool (http://discover.usvao.org)]. Clicking on the "Launch Beta Version" button (highlighted) gives us the search window. (2) We enter a position and search radius in the search box - in this case, we'll use the position 288.562623, 50.935801 and a search radius of 0.002d (all in decimal degrees - different formats are possible).

(3) This queries all the data sets registered with the VO and brings up a list of what's available. Facetted browsing allows us to select the type of data available (in this case, we choose light curves), the archive source, etc. The count refers to the number of data sets available.

(4) Having selected the light curve data set, we see that, in this case, it is Kepler and that 3 records are available. We load these records into a new table:

(5) We pick the first one and get some summary information for it as well as links to download it, plot it: or send it to an analysis service such as the NStED periodogram service: or the (prototype) Caltech Time Series Characterization Service:

(6) The real power of the VO, however, is that we could just easily have done this for data from the HTSC: as from CRTS: as from any data provider that we know about. And you don't need to do this just through the VAO Data Discovery Tool - you can access the data yourself and send it to whichever tool you want (as long it supports the VO common formats and access protocols).
