Systems and the "Hyg" database

There are two sorts of analysis it occurs to me that I have not done yet with these data.
  1. I have not attempted to group the individual records into "systems".  I can tell from the spectral data that many "star" entries are close multiples, but I have not looked to see how many have even identical X/Y/Z coordinates let along those indicating close grouping.  In terms of data reduction I think that is my first step.
  2. I have not looked how I will want to look at the reduced data when I am done, and to wold-build and record non-generated information on to of that.  No knowing a good chunk of  the endpoint is premature and I need to address it.
