SALT spectrum of PGC 50427, zoomed onto the Hα line. The dotted black curve represents the spectrum after subtracting the narrow [NII]λλ6548, 6583 emission lines. The narrow Hα and [NII] models are shown in dotted lines at the bottom of the Hα profile. The NB 670 and SII filters efectively covers the line between velocities −3478 km s^-1 and +1881 km s^-1 (red dotted lines) and −1201 km s^-1 and +1479 km s^-1 (blue dotted lines) respectively.
