des_dr2The DES is a 5000 square degree grizY photometric survey of the Southern sky aimed at understanding the accelerating expansion rate of the universe using four complementary methods: weak gravitational lensing, galaxy cluster counts, baryon acoustic oscillations, and Type Ia supernovae.des_dr2.main(paragraph adapted from the <a href="https://arxiv.org/abs/2101.05765" target="_blank" rel="noopener">DES DR2 paper</a>) "DR2_MAIN includes all the main quantities extracted from the coadd pipeline and important information about the objects.
