Bayes factors obtained for different models.
Model comparison | Bayes factor |
---|---|
CGW+PSRN vs PSRN | 4000 |
CGW+PSRN+CURN vs PSRN+CURN, 3 bins | 12 |
CGW+PSRN+CURN vs PSRN+CURN, 9 bins | 4 |
CGW+PSRN+GWB vs PSRN+GWB, 3 bins | 1 |
CGW+PSRN+GWB vs PSRN+GWB, 9 bins | 0.7 |
Notes. Bayes factors obtained for different model comparisons indicate how much the data favour the inclusion of a continuous gravitational wave (CGW) with Earth and the pulsar term. The first comparison considers adding a continuous gravitational wave to the pulsar custom noise (PSRN). The second and third model comparisons include an additional common uncorrelated red noise CURN modelled with a power-law with 3 or 9 frequency bins. The fourth and fifth model comparisons include a gravitational wave background GWB modelled with a power-law with 3 or 9 frequency bins.
