SATCON2 Algorithms Working Group Report

We have attempted to transform the SATCON1 recommendations into a specific set of high-level software requirements with provisional names for convenience of reference. We note that each of these is a fairly major software effort if they are to be robust enough to support the community. However, in some cases relevant software already exists, and this document identifies those packages. In brief, the SATCON1 recommendations call for the ability to flag, mask and repair satellite trails affecting astronomical data (a software tool we call TrailMask), to predict when satellite trails may or will affect specific observations (which we call PassPredict), and to simulate the effects of satellite trails so that the community can assess the scientific impact of those effects on astronomical research.
