Table 1
Main survey and instrument specifications.
| Radius of reflector | 300 m |
| Aperture of dish | 500 m |
| Illuminated aperture | 300 m [500 m] |
| Opening angle | 100 degrees to 120 degrees |
| Zenith angle | 40 degrees |
| Tracking range | 4 to 6 h |
| Frequency coverage | 0.4 to 1.42 GHz |
| Total system temperature (Tsys) | 20 K |
| Sensitivity (L band) | Antenna effective area/system noise temperature ~2000 m2 K-1 |
| Angular resolution (L band) | 2.9 arcmin [we assume 5 arcmin over the range 0.4 to 1.42 GHz] |
| Number of beams (L band) | 19 [we assume more than 19 receivers and feeds] |
| Pointing accuracy | 8 arcsec |
| Integration time per pixel | 4 s |
| Pixel bandwidth in z direction | 0.3 per cent |
| Redshift range of survey | 0.5 to 2.5 |
Notes. Most of these details are provided in Nan et al. (2011) and Nan & Li (2013). Wherever our calculations assume some figures that are slightly different from the official FAST specifications, these are given in square brackets. We note that the project anticipates that more than 19 receivers and antennas will be built. The main factor that will determine this is the cost and effort of building and installing them.
