This is one of the lower-quality surveys, with varying noise and some questionable baselines. In addition, two different filterbanks were used over the course of the survey, one with 1.3 km/s channels and 333 km/s of coverage, and the other with 0.26 km/s channels and 67 km/s of coverage. In the present cubes all spectra were interpolated onto a grid with 1.30 km/s spacing. |
