How do I...Find data for all objects in a given RA/Dec/Magnitude/Absolute Magnitude range?You can use the SDSS search tools to find all objects that meet certain criteria, such as position, magnitude, color, or absolute magnitude. For position, magnitude, and color, you can use the Imaging Query Form (link opens in a new window). For absolute magnitude (and any other criteria), you can write queries in SQL (new window). See the directions for using the Imaging Query Form on the next page to see how to use the form's general features. Then see the RA and Dec and Magnitude pages of this guide to learn how to search for those parameters. See the Absolute Magnitude page to learn how to use SQL to search for objects by absolute magnitude. |
