The center coordinate and search radius are required input parameters. Other parameters are optional. In the
range search, min. value <= results < max. value. Therefore, if you want to find
objects which have exactly same value as your input, type the same number as min. and max. values.
If you want to select objects that are matched to SIMBAD, 2MASS, SDSS, and GALEX objects, click the relevant
check boxes.
