In PALISADE, CKKS is configured to use $\alpha = 8/q$ (using the definition of $\alpha$ in the LWE estimator). This corresponds to the standard deviation of $8/\sqrt{2\pi} \approx 3.19$. This value was chosen based on the HE security standard at https://homomorphicencryption.org/standard/ You can manually change this value from 3.19 to something else by ...
