Paper: Unsmearing Kinematic Signatures of Protoplanets

The exoALMA survey presented the unprecedented opportunity to map gas motions induced in the natal discs of newborn planets. However, such measurements are biased by an instrumental effect called beam smearing, leading to the underestimation of velocity perturbations and planet masses. We built an applied a probabilistic tool to correct for this.
