Table 1.
Values of the amplitudes of the main (a0) and secondary (a2) lobes (in units of dBi) obtained with GRASP for the analysed beam patterns of Grueff and SRT radio telescopes.
| Frequency | Telescope | a0 | a2 | Δa | Roff |
|---|---|---|---|---|---|
| (GHz) | (dBi) | (dBi) | (dBi) | (arcmin) | |
| 18.3 | Grueff | 73.5 | 53.0 | −20.5 | 3.1 |
| 25.8 | Grueff | 76.2 | 48.0 | −28.2 | 2.7 |
| 18.8 | SRT | 80.4 | 61.4 | −19.0 | 1.5 |
| 24.7 | SRT | 82.9 | 60.8 | −22.1 | 1.3 |
Notes. Δa reports the difference between a2 and a0, and Roff indicates the offset (in units of arcmin) between the secondary and the main lobes centroids.
