Fig. B.2


2D spectra of the “low-z”, low-redshift galaxies obtained with SDSS mask. The spectra are aligned in wavelength. The top panel shows SDSS28 with the highest KAB band mag of 17.65. These sources spanned KAB band magnitudes from 17.65 (SDSS28), 19.39 (SDSS12) to 20.46. In the center of the stripes (~19 000 Å), the decrease in flux indicates the wavelength region of strong atmospheric absorption. We can also see regions of high Poisson noise due to sky emission lines.
