Go to the SQL Search tool
(link opens in new window). From the astronomers' main page, look under Search Tools. From the
public main page, look under SkyServer Tools, then Search.
In the main window, type the following query (or run the query from the query box at the bottom of
this page):
SELECT objID, ra, dec -- get object ID, ra, dec of binary star |
|
FROM PhotoPrimary -- From all primary objects (best detections) |
|
WHERE u - g < 0.4 -- Search based on known colors of CVs |
AND g - r < 0.7 |
AND r - i > 0.4 |
AND i - z > 0.4 |
The query returns the object ID, RA, and dec of each binary star. By changing the color
constraints (such as u - g < 0.4) to the color constraints of another type of object you want
to find, you can search for those objects instead.
Use the query box below to practice running the query shown above. You can modify the query to return other data if
you want. Click Submit to run the query or Reset to reset the query box.
