 - In the 2 Dimensional case 
 we use  a potential of the form:
-$`\Phi _p^{\epsilon} = -{m_pG\over {\sqrt {d^2+\epsilon^2}}}`$
+$`\Phi _p^{\epsilon} = -{m_pG\over {\sqrt {d^2+(\epsilon R_H)^2}}}`$
 In 2 dimensional models we do not only have the problem of avoiding the singularity but we choose a potential that allows to mimic the average influence  that the planet would have  on the vertical gas column.
 A value often used for the smoothing is $`\epsilon = 0.7H`$ where $`H`$ is the disc  scale height.
