The NA48/2 experiment at the CERN SPS carried out data taking in 2003 and 2004. Analysis of the selected data samples of 7,146 K^±→π^± e+e- decay candidates with 0.6% background, 1,164 K^±→π^±γγ candidates with 3.3% background, and 120 K^±→π^±γe+e- candidates with 6.1% background allowed precise measurements of branching fractions and other characteristics of these rare kaon decays.
