Usage of Sloan Digital Sky Survey / SkyServer / Explore Tool     Back to "Investigate about Star" Open the following page. Sloan Digital Sky Survey / SkyServer / Explore Tool http://skyserver.sdss.org/edr/en/tools/explore/ First of all, click "Click here to Explore!". Then the Sky Server Explore Tool page will be displayed. For example, let's investigate about an object at R.A. 00h15m58.4, Decl. -00o18'15". This object is a galaxy named NGC 60 = PGC 1058. Get Information Find "Search by" in the left side menus, and select "Ra,dec". Then a small dialog will be displayed, so input the required parameters. Ra Input the R.A. in degree. R.A. 00h15m58.4 is converted into degree as ( ( 58.4 / 60 + 15 ) / 60 + 0 ) * 15 = 3.993. So here input as "3.993". Dec Input the Decl. in degree. Decl. -00o18'15" is converted into degree as - ( ( 15 / 60 + 18 ) / 60 + 0 ) = -0.3042. So here input as "-0.3042". Push the "OK" button, and the information, data, images, spectrums, etc., of this object will be displayed. Get Further Detailed Information After the information of this object is displayed, select "NED search" in the left side menus. Then the further detailed information will be displayed. View Image After the information of this object is displayed, find "PhotoObj" in the left side menus, and select "Navigate". Then the image will be displayed. Click your mouce on the image. Then the R.A. and Decl., type and magnitudes in five bands (u', g', r', i', z') of an object at the clicked position will be displayed. View Image and Get Further Detailed Information After the information of this object is displayed, select "Virtual Sky" in the left side menus. Then the image will be displayed. Choose "Galaxy" from the "Clicking on sky will:" items and click your mouse on the image. Then the NED database is searched and the further detailed information of a galaxy at the clicked position will be displayed. Choose "Star" from the "Clicking on sky will:" items and click your mouse on the image. Then the SIMBAD database is searched and the further detailed information of a star at the clicked position will be displayed.
