Re: Minimum spanning circles and Voronoi diagrams

Chris,

The present data sets have a minimum of 56 possible measurements of each 
star in each filter.  So far for most stars it is much higher than 
this.  About 150 points.  So we have much better statistics than we had for 
the Mark III.  I am just trying to initiate thinking about how to make use 
of this.
