VAST void catalogs for SDSS DR7

Version 1.1 of the void catalogs; updated files are italicized. The peer-reviewed publication for these catalogs is submitted to the Astrophysical Journal Supplemental Series, an American Astronomical Society journal. A preprint of the paper is available at https://arxiv.org/abs/2202.01226; please cite this article when using any of these catalogs.

We provide three void catalogs using a volume-limited subsample of the SDSS DR7 using new implementations of two different void-finding algorithms from the Void Analysis Software Toolkit (VAST): VoidFinder and Voronoi Voids (V²). We identify 1159 cosmic voids with VoidFinder, 534 with V² using VIDE pruning, and 518 with V² using REVOLVER pruning.  These catalogs exist within the SDSS DR7 main survey volume, out to a maximum redshift of 0.114. Effective radii and centers for all voids are computed and included with the catalogs; the median void effective radius is 15-17 h^-1 Mpc for all three catalogs, and none have an effective radius larger than 54 h^-1 Mpc.

All catalog files are in ASCII format with commented headers.  An example of each file (except the galaxy file associated with V²) is shown in Tables 1-5 in the associated journal article. For each galaxy in the _galzones.dat files, the value in the gal column is the same as that in V2_nsa_v1_0_1_gal.txt.  Guidance on how to use these catalogs can be found at https://vast.readthedocs.io/en/latest/.
