Radial profile of the deviation from the Keplerian frequency. Purples curves refer to the RAMSES run and blue curves refer to the PLUTOx8 run. The Keplerian frequency is corrected by the sink softening length (Eq. (6)). For each radius, we compute the azimuthal median and average it in time (as indicated in the plot legend). The use of a median is meant to get rid of non-axisymmetries such as spiral arms (see OK20). The gray area points to a deviation of ±10% with respect to Keplerian frequency. The vertical line indicates the sink cell radius in PLUTO runs. Until t~12 kyr, disks are comparably Keplerian in RAMSES and PLUTOx8.
