The first PLATO Stellar Science (WP120 STESCI) meeting after the ESA M3 selection was held on April 9th-10th 2015 in Paris. The goal was to produce at the end of the meeting a preliminary draft of WP120 Definition document that will describe the specifications of the methods and procedures for accurately characterising the stars of the core program. The internal and external inputs/outputs were detailled as well as the interface procedures between the WPs within WP120 and with the Plato Data Center (PDC). This document was requested as part of the internal Consortium data package.
The meeting was organised in plenary sessions as well as an afternoon splinter session. There was be 5 working groups (description below). For each stellar property considered as an output a the working group, the specification document (a preliminary draft) had to contain for instance:
- output: definition and/or description, required PLATO specification
- inputs: definition and/or description, specification of the quality of the input needed to provide the output satisfying the requested Plato specification
- tools: methods (to obtain the output and its uncertainty) and procedures to run these methods
- interfaces with PDC
- tests and simulations, observations
- identification of biases keeping from reaching the specifications
- the work to be done before adoption (beginning 2016)
There was also a list of questions (general or specific to each working group) to be answered.
