new catalog - now with ellipticities!

We have released a new catalog with a bug fix and several new additions:
  • The central density cut was not applied to the catalogs due to a bug. Thus the "centers_" and "centers_nocut_" files were the same. We have corrected this.
  • We have used a higher resolution HEALpix map for calculating the area of the survey mask and hence have more precise estimates of the volume and mean galaxy separation of the sample. The mean separation for all Main Sample volume-limited samples is now lower, so there are correspondingly more voids. But please remember to use the smallest voids with caution and at your own risk.
  • We now include highly preliminary ellipticity information - the eigenvalues and eigenvectors of the moment of inertia tensor for each void is in the "shapes_" file.
