Parameters used to calculate the minimum detectable flux density of the IRAM 30m survey, and for comparison, a potential Galactic centre pulsar survey with phased ALMA.
| Tsys | G | np | tint | Δν | δ | Smin | |
|---|---|---|---|---|---|---|---|
| (K) | (K Jy−1) | (h) | (GHz) | (mJy) | |||
| 30m | 125 | 0.16 | 2 | 3.0 | 32 | 0.1 | 0.059 |
| ALMA | 70 | 1.05 | 2 | 5.0 | 8 | 0.1 | 0.008 |
Notes. Columns indicate the system temperature (Tsys), the telescope gain (G), the number of polarisations (np), the on-source integration time (tint), the instantaneous bandwidth (Δν), and the duty cycle of the pulsar to be detected (δ). The values are chosen to represent a sensitive observation at a frequency of 120 GHz. In both cases the signal-to-noise ratio required for the detection, (S/N)min, is set to 6.
