We perform numerical simulations to determine the shear stress and pressureof steady-state shear flow in a soft-disk model in two dimensions at zerotemperature in the vicinity of the jamming transition \phi_J. We use criticalpoint scaling analyses to determine the critical behavior at jamming, and wefind that it is crucial to include corrections to scaling for a reliableanalysis. We find that the relative size of these corrections are much smallerfor pressure than for shear stress. We furthermore find a superlinear behaviorfor pressure and shear stress above \phi_J, both from the scaling analysis andfrom a direct analysis of pressure data extrapolated to the limit of vanishingshear rate.
