TL;DR: In this article , the authors present the design of the Merian filter set: N708 and N540, which are two medium-band filters on the 4-meter Victor M. Blanco telescope at the Cerro Tololo Inter-American Observatory, with the goal of carrying the first high signal to noise (S/N) measurements of weak gravitational lensing around dwarf galaxies.
