This survey is also incorporated into the large second quadrant surveys (DHT17 & DHT18). However, in those surveys the CasA spectra are smoothed and interpolated onto a channel spacing of 1.300 km/s. In addition, in DHT18 the data are spatially smoothed and interpolated onto a 1/4° grid. Thus, the original survey given here, with beamwidth sampling and 0.65 km/s velocity resolution, should be used when possible. |
