Table 1: Properties of suggested polarisation calibrators at the MeerKAT L-band.
Calibrator | RM (rad / m2) | Fractional linear power (%) | Average linear angle (deg) | S1.28GHz Total intensity (Jy) |
|---|---|---|---|---|
3C 286 | 0.00 +/- 0.2 | 8.6 to 9.9 | 33 | 15.77 |
3C 138 | -0.80 +/- 0.3 | 5.6 to 8.4 | -14 to -10 | 8.99 |
While we have identified 10 new polarised sources with low (< 10 rad/m2) rotation measure, we have only recently started a monitoring programme to determine their long-term stability. Users interested in using one of these potential calibrators should contact the helpdesk when setting up their observation for scheduling.
