kinematic dipole and dust

I had a long conversation with Kate Storey-Fisher (NYU) and Abby Williams (Caltech) about the dipole in the Quaia catalog caused by the kinematic motion of the Solar System barycenter with respect to the cosmic rest frame. Williams has found that the amplitude of the dipole we get depends very strongly on how we account for dust in our sample. There is currently a controversy about the amplitude of the dipole seen in WISE quasars. We now think that it is possible that the measured amplitude is a strong function of how dust is corrected for in the sample? We designed new tests for next week.
