 Question: What type of distribution is used to model the probability of non-linear density field?
 Answer: A superposition of a Gaussian and a lognormal distribution.
 
 Question: Can the shape of central cluster galaxies be used as a predictor of weak-lensing mass bias in individual clusters?
 Answer: Yes, we find that on average, the lensing masses of clusters with the roundest / most elliptical 25% of BCGs are biased ~20% high / low compared to the average.

 Question: What could be the cause of remaining excess power in a signal after foreground mitigation?
 Answer: Residual foreground emission from sources or diffuse emission far away from the phase centre, polarization leakage, chromatic calibration errors, ionosphere, or low-level radio-frequency interference
