1. Work packages and early schedule WP1 - Mechanical design 6 JB Daban -F Fressin -F Valbousquet -K Agabi -OCA groupe projet -LUAN groupe projet  Design of telescope tube structure, telescope to mount fixation  Early discussion on design with groupe projet (Sep ? Oct ?): Karim, JB, Franck: list of needed specifications – Heike Anders, Frederic tolerance on changes on PSF shapes for image substraction  Choice of the telescope size to be done according to telescope mount at the end of October and realisation

2. Work packages and early schedule WP2 - Telescope and Camera software -A Klotz -A Blazit -C Combier -K Agabi – organizing discussion -A le Van Suu -C Carol  Study of telescope guiding and tracking software and camera reading. Computer interfaces/redundancy/security  Meeting between LUAN and OHP teams soon (Sep ? Oct ?) to fix which software can be reused/adapted for A STEP

3. Work packages and early schedule WP-3 Camera thermal enclosure design and tests/ filter and field corrections – > subcategory of WP-1 -A Blazit -JB Daban -F Jeanneaux -Y Fantei -F Fressin -K Agabi  Design of enclosure for camera / wynne corrector /filter or dichroïc, fixation on telesope tube

4. Work packages and early schedule WP-4 Optical combination – Camera tests A Blazit V P Assus F Fressin A Erikson + F Pont in reaction mode – F Valbousquet real input  Zeemax simulations of the field – PSF shapes on every part of the field.

5. Work packages and early schedule WP-5 - 2007 campaign tests -D Mekarnia V -FX Schmider -E Fossat -K Agabi + F Valbousquet V + V : optical experiments – small mirrors including tulip mirror in zerodur September  Logistic needs for A STEP : to be defined for September 11  Checking the availability of new “optical experiments” site at Dome C, or preparing A STEP for Concordiastro site  Testing specific treatment on zerodur mirror at different places – behaviour of frost - optical behaviour of mirrors Foucault test  What do we send at Dome C in 2 months ?  Additional tests on Astro 1200 ? Different payloads ?

6. Work packages and early schedule WP-6 Dome C specific problems: open questions that require study groups - Karim V  How to do flat fields at Dome C ? Mandatory for good photometric precision – frequency needed ?  Necessity of a protection for bad condition days/summer ? Availability of “flower domes” ?  Electrical problems/overcharges – all electronic control  Duplication ? Of camera ? Encoder (mount) Control computer  Who will run A STEP in 2007 ?

7. Work packages and early schedule WP–7 Data pipeline – Light curves extraction and analysis -H Rauer V -A Erikson -F Pont -T Guillot -FX Scmider -F Fressin  What is reused from BEST data pipeline ? Design of the alarm mode and photometric control. What has to be fixed before A STEP departure for Dome C?  Need to drive A STEP on sky in France before computing the real pipeline – define specific alarm mode too –  Proposal: input from Heike – development as a team approach – raise fundings – archiving A STEP data – Proposal fro A STEP/BEST 2 comparisons/summer/winter network - internal DLR funding application by spring 2007

8. Work packages and early schedule WP-8 Target fields selection – survey strategy -T Guillot -FX Schmider -F Pont -H Rauer -C Moutou -M Deleuil -S Aigrain -F Fressin  Need for preliminary observations – or data base on target fields ? Specific needs for seismology targets ?  Target field selection from Holger thesis  Starting discussion with Marseille field selectors for CoRoT

9. Work packages and early schedule WP-9 Data analysis – Follow up of candidates -T Guillot -FX Schmider -F Pont -H Rauer -A Erikson -F Bouchy -F Fressin -S Aigrain -C Moutou  What is necessary to fix soon ?

10. Work packages and early schedule WP-10 Future prospects – the best design for global transit search -T Guillot -H Rauer -Y Fantei : internet site soon -A Erikson -F Pont -FX Scmider -F Fressin  comparative simulations with CoRoTlux – experience from BEST-2 – A STEP connection and CoRoT preliminary results  Necessity to propose different designs soon for visibility and outreach ?  Developping webpage / internal and public ?
