The data available here correspond to maps of the tidal forces in the local Universe extracted from the 2MASS galaxy survey using the method described in the companion paper. The data are available as HEALPix maps with resolution parameter Nside=64, and are based on a reconstructed density field computed using a Gaussian smoothing kernel of standard deviation 1o. The maps and contain the mean and covariance of the components of the 2D tidal tensor and its eigenvalues, as described in the pape... Expand documentation
