Example of confusion between broad G-band absorption and the 4000 Å break. The data are represented in black, the flux errors on each pixel in red, and the template in blue. A boxcar smoothing kernel of width 11 pixels has been applied to the data for illustrative effect. Left: the template corresponding to the visual inspection redshift is fit to the data with a χ2 per degree of freedom of 1.258 at a redshift z = 0.64375. Right: an incorrect template is fit to the data with χ2 per degree of freedom of 1.264 at z = 0.82202, a difference from the first template small enough to trigger the ZWARNING_NOQSO flag.
