Query VO resources for a given region of a sky

Note: DataScope V2.1 released March 26, 2007 (many cosmetic changes and some bug fixes)

What do we know about a given point or region in the sky?

To find out, just enter a target or position. The NVO DataScope will show you the results from hundreds of resources.

Position:
	Use a target name (e.g., 3c273) or position (e.g., 10 10 10.1, 20 20 20.2)
Size:	(in degrees, max is 2)
Run query:
Skip cache? Refresh registry?

Some recent queries:

04:22:54.66, -25:07:46.2 (0.1333)

45.5332, -54.4099 (0.25)

67.50, -48.67 (0.25)

315.2665832,9.7636770 (0.0125)

228.753 48.7949 (0.05)

Positions may be entered in decimal (dd.f, sdd.f) or sexagesimal (hh mm ss.f, dd mm ss.f) notation or as targets recognized by NED or SIMBAD.

The Size should be entered in decimal degrees.

Use the Skip cache flag to ensure that you get the latest results from all services.

The Refresh registry flag queries the VO registry to get the latest services. The registry is normally queried every hour.

By default the last few queries anyone has made are shown at the bottom of the page but there is a checkbox to keep your query from being recorded on this list.
