A comprehensive survey of emission-line galaxies at z<1.5 based on data from two narrow-band filters (NB816 and NB921) is conducted in the UltraDeep and Deep layers. The NB816 and NB921 data are available in 5.7 deg^2 and 16.2 deg^2 respectively in the Public Data Release 1. The 5sigma limiting magnitudes are 25.2 (UltraDeep, 1.4 deg^2) and 24.8 (Deep, 4.3 deg^2) mag in NB816, and 25.1 (UltraDeep, 2.9 deg^2) and 24.6-24.8 (Deep, 13.3 deg^2) mag in NB921.
We construct unprecedentedly large samples of 8,054 Halpha emitters at z ~ 0.25 and 0.40, 8,656 [OIII] emitters at z ~ 0.63 and 0.84, and 16,877 [OII] emitters at z ~ 1.19 and 1.47. The emission-line galaxies cover a wide range of luminosity, stellar mass, and environment. Table 3 of Hayashi et al. (2017) summarizes the samples of emission-line galaxies.
