Overview
Here we report the watershed void catalogues that were described in () and employed in various DES Y1 papers (). These catalogues are obtained by running VIDE (a popular watershed void finder, described here XXX) on the latest Y1 catalogues of redmagic galaxies and redmapper clusters. We also provide the void-catalogues obtained in the same manner, albeit using mocks (extracted by the MICE 2 simulations).

For each run of VIDE we include two tables that contain different info on the same void sample. The first table includes the "sky positions" (RA, dec, z), void radius, and void ID. The second table ("center central") includes the following columns: volume-weighted centre x,y,z [Mpc/h], volume [normalised by mean volume per tracer particle], effective radius [Mpc/h], redshift, volume [Mpc/h^3], void ID (unique id of the void), density contrast, num part (number of tracer particles included in the void), parent ID (ID of the parent void), tree level (level occupied in the nested void structure), number of children (number of sub-voids), central density (density within 1/4 of the void radius, in units of mean density). All of these labels are also reported in the header of each file.
These catalogues are complementary to those listed above, but include more properties, namely: volume-weighted centre x,y,z (Mpc/h), volume (normalized by mean volume per tracer particle), effective radius (Mpc/h), redshift, volume (Mpc/h^3), void ID (unique id of the void), density contrast, num part (number of tracer particles included in the void), parent ID (ID of the parent void), tree level (level occupied in the nested void structure), number of children (number of subvoids), central density (density within 1/4 of the void radius, in units of mean density). The names of the columns are also reported in the header of each files. In order to match these catalogues with those posted in the section below, you need to use the void ID.
