Dark Energy Survey Year 3 results: redshift calibration of the <scp>MagLim</scp> lens sample from the combination of SOMPZ and clustering and its impact on cosmology
ABSTRACT We present an alternative calibration of the MagLim lens sample redshift distributions from the Dark Energy Survey (DES) first 3 yr of data (Y3). The new calibration is based on a combination of a self-organizing-map-based scheme and clustering redshifts to estimate redshift distributions and inherent uncertainties, which is expected …
