Here are some sample plots produced using the SM programmes as described on the Concordance home page:
Figure 1 (1.2 Mb): Sample all-sky view of the Concordance. Each entry in the various catalogues is represented as a circle approximating the object's size, where size information is available. Objects can also be labelled with a name, and distance where available, although this is not done here for clarity. Shown here are all catalogues except the NGC 2000.
Figure 2 (128 kb): Concordance of all catalogues with entries in the area around M42, the Orion Nebula, plotted with label verbosity 1 (names only).
Figure 3 (224 kb): Concordance of all catalogues with entries in a window spanning galactic longitude 40°-50°, plotted with label verbosity 2 (names & distances).
