Orbiting Binary Indication

You may start to notice a few of the Primary IDs are listed in bold and red.  I'm now using this to indicate a confirmed binary that has a measured secondary orbit.  An example of this can be found in the challenging doubles in Leo list.  I'll eventually go back through some of the older lists and also make this notation where I didn't previously.  At some point, I may even create special lists of only true orbiting visual binaries.  It seems like there might be some interest in this, especially for amateurs who want to attempt to make astrometric measurements themselves.
