Example of performance of new peak finder compared to the original one. To illustrate the difference between peak finders, we show a quasar with magnitude r = 19.9224 and redshift of z = 2.12 (top panel), a galaxy with magnitude r = 19.4995 and redshift of z = 0.07 (mid panel), and a star with magnitude r = 19.4182. Blue circles show the peaks as detected by the original peak finder. Orange squares are the peaks detected by the new peak finder. Dashed lines indicate the expected position of the main emission lines. For the quasar, from left to right, they indicate the Lyα, Si IV, C IV, C III], and Mg II. For the galaxy, also from left to right, they indicate the O [III] and Hα.
