SALT spectrum of PGC 50427. For illustration, the band passes of the filters used for the photometric monitoring are shown (blue B-band, green R-band, orange r_s-band, red 670-band, and brown for SII-band). The NB 670 and SII catches the redshifted Hα line, its flux is composed by the contribution of about 85% Hα line and 15% continuum. We note that for actual flux calculations the filter curves are convolved with the quantum efficiency of the Alta U16 and SBIG STL CCDs cameras.
