Ideas, provisional plans and known unknowns for the Source Environment Analysis

Abstract

This document contains the current state of thinking on how the Source Environment Analysis will proceed. The reader should take note that these plans are still provisional. The cumulative total of CPU time and resources required for the full source environment analysis for all sources is prohibitive. The planning for this package must therefore address and consider methods to reduce the computational burden. It may be that the exact pipeline is not defined until it is tested in place on the infrastructure on which it will be run. The idea will be to optimise what may be achieved with this package based on the available resources. This document also seeks to identify and present all the current known uncertainties of the processing and interactions with the rest of the Gaia analysis. We also wish to start a dialogue with the community about the priorities and expectations for this package in order to achieve our aim of successfully prioritising which processing to perform, and in order to aid in the revelation of what we have failed to consider in our planning.
