Service Documentation

As a short example for how to explore this data using VO protocols, try this:

• Open TOPCAT and it's VO/TAP window. Select "GAVO DC TAP" from the server selection and hit "use service".

• We would like to find "unusual" time series; perhaps ones with a large range. To get a feeling for what "unusual" might mean, just fetch a few metadata rows like with a TAP query like this:

  SELECT TOP 7000 * FROM rome.time_series
  WHERE np_i>100 AND np_g>100
  

• Do a plane plot of that data, and ask TOPCAT to plot mag_i_max-mag_i_min against mag_g_max-mag_g_min.

• When you open a table view, you can inspect the metadata for the time series when clicking on a point in the plot.

• Let's inspect the actual data: In TOPCAT's main window, do Views/Activation Actions. If you check "Plot Table", TOPCAT will download and plot the time series; it will only plot the first lightcurve, though. To get all bands, at this point you have to manually fetch accref from the table and use File -> Load Table. Sorry about this.

• Using datalink, you can also view three-band previews with one click on a plot point. To configure this, check "Invoke Service" in the Activation Actions, then use "Invoke now". In the dialog that pops up then, select the row with #preview and check Auto-Invoke. You will then see a light rendition of the light curves in (up to) three colours.

Your desktop could then look somewhat like this:

Overview

You can access this service using:

• static -- static (i.e. prepared) data or custom client-side code; probably used to access ancillary files here
• dlmeta -- a datalink interface for discovering access options (processed data, related datasets...) for a dataset. You usually need a publisherDID to use this kind of service. For special applications, the base URL of this service might still come handy: http://dc.g-vo.org/rome/q/sdl/dlmeta
• dlget -- a datalink interface letting specialized clients retrieve parts of datasets or discover related data. You use this kind of service exclusively in combination with a pubdid, usually via a direct link.
