DP01

DP01 refers to the primary dataset released by the Dark Energy Survey (DES). The Dark Energy Survey was a project that mapped millions of galaxies and thousands of supernovae to study dark energy, a mysterious force believed to be driving the accelerated expansion of the universe. DP01 is the first major data release from this comprehensive observational campaign. It contains a wealth of information that astronomers use to analyze the properties of dark energy and its influence on cosmic evolution. The data includes imaging from the Dark Energy Camera (DECam) located on the Victor M. Blanco 4-meter Telescope in Chile, as well as catalog data derived from these images. This catalog provides precise measurements of galaxy shapes, positions, and photometric redshifts, which are estimates of galaxy distances based on their observed brightness across different filters. The release of DP01 has been a significant event for the astronomical community, enabling numerous research studies and contributing to a deeper understanding of the universe's fundamental components and history. Subsequent data releases from DES have built upon the foundation laid by DP01.
