Photometric Constraints

Photometric Constraints are applied to Flux Density or Magnitude. Flux Density (or Magnitude) may be Unconstrained or constrained to be Available, Brighter Than or Fainter Than the entered Flux value, or Between, or Not Between two entered values. If Available is selected, then only objects with photometric measurements will be returned. Flux (or Magnitude) Units of Jy, mJy, Magnitude, or W/m^2/Hz may be selected. Select one of eight broad Photometric Bands (i.e. spectral regions) to constrain: Infrared, Radio, Millimeter, Sub-Millimeter, Optical, Ultraviolet, X-ray, or Gamma Ray flux density. Next, use the "Select one" menu to select a specific band within one of these spectral regions.
