Dark colours show underdense regions, bright colours are overdense.
A novel interpolation scheme has been used across the galactic plane. We live at the center. Some higher resolution images are available at the Durham PSCz page. There are many science questions to be addressed, such as quantifying large-scale galaxy clustering, the origin of our motion with respect to the microwave background, and the comparison between the density and velocity fields of the local universe. We measured the remaining 4500 ourselves.
