arxiv.org/abs/2601.02462 Exposure-averaged Gaussian Processes for Combining Overlapping Datasets
The paper presents a Gaussian process framework that accounts for finite exposure times by integrating the usual instantaneous stellar-variability kernels. It also models relative instrumental drift, enabling Sun-as-a-star radial velocity datasets from overlapping instruments to be combined.
