PS1 lens candidates with multiple emission lines from a high-redshift background galaxy overlaid on the SDSS BOSS spectrum of the foreground LRG. The black, gray and blue lines show the observed spectrum, the 1σ noise level, and the best-fit SDSS template for the LRG, respectively. The spectrum is zoomed on the spectral features associated with the background line-emitter rather than with the LRG. Top: PS1J2345−0209 with z_LRG = 0.2940 and z_s = 0.6581. Middle: PS1J1134+1712 with z_LRG = 0.3752 and z_s = 0.8121. Bottom: PS1J1724+3146 with z_LRG = 0.2097 and z_s = 0.3461.
