Linear estimator measurements of dipole amplitude (d) and dipole declination (Decd) for 100 simulated maps containing 106 sources (for the full sky) and an observer velocity of v = 1200 km s−1 towards RA = 180 deg and 
, the source count of the simulated sources behaves as n(> S) ∝ S−x with x = 1 and the spectral index of the sources is α = 0.75, leading to an expected dipole amplitude of d = 1.5 × 10−2.
| Mask type |  |
Measured d | Measured Decd |
|---|---|---|---|
| (deg) | (×10−2) | (deg) | |
| Caps | −40 | 1.565 ± 0.017 | −14.95 ± 0.44 |
| Ring | −40 | 2.016 ± 0.026 | −74.60 ± 0.38 |
| Caps | −10 | 1.917 ± 0.024 | −3.21 ± 0.38 |
| Ring | −10 | 0.915 ± 0.018 | −35.84 ± 1.30 |
Notes. Masking sources within −40 deg < δ < +40 deg for the ring type mask and with either δ > 40 deg or δ < −40 deg for the caps type mask.
