The disk self-gravity alters both the planet's angular velocity and the disk's rotation profile as:

where is the planet's orbital radius, denotes the Keplerian angular velocity, and:

where is defined as ASPECTRATIO, as FLARINGINDEX and as SIGMASLOPE. When the disk self-gravity is taken into account, the initialization of the planet's angular velocity is done by function init_planetarysys_withSG in sgsysinit.c, while that of the fluid elements is done by function init_azimutalvelocity_withSG in sgvelinit.c.
