Lossy Compression of Weak-Lensing Data

Massey, Richard; Rhodes, Jason; Bernstein, Gary M. +4 more

Future orbiting observatories will survey large areas of sky in order to constrain the physics of dark matter and dark energy using weak gravitational lensing and other methods. Lossy compression of the resultant data will improve the cost and feasibility of transmitting the images through the space communication network. We evaluate the consequen…
