The paper “Gap interpolation by inpainting methods : Application to Ground and Space-based Asteroseismic data” has been accepted for publication in A&A. This paper is describing the software K-inpainting.

The software K-inpainting has been developed to handle the problem of missing data in the asteroseismic signal of Kepler. This technique, based on a sparsity prior, enables to judiciously fill-in the gaps in the data, preserving the asteroseismic signal, as far as possible.

More recently, it has been implemented in the CoRoT pipeline to process the data from missing data.

The K-inapinting software is available here
