For the asteroseismology channel

The database contains all the stars brighter than mV = 9.5 (~ 12000 objects) with extensive data from:

• The CDS/Simbad database

• Dedicated ground based spectroscopy and strömgren photometry for stars brighter than mV = 8; under the resp. of C. Catala (LESIA)

• Specific catalogues identifying various types of stars (δ-scuti, β-Cep, …); under the resp. of W. Weiss (U. of Vienna).

These informations will be used for the core and secondary programmes (long runs), the exploratory programmes (short runs) and the additional programmes (during both short or long runs) in the seismology fields.

For the extra-solar planet search channel

The database contains stars in the range of magnitude mV between 12 and 16 with data from:

• Dedicated ground based BVRI photometry and exhaustive identification of ~ 3,000,000 stars in the exoplanet fields around the principal targets; under the resp. of M. Deleuil (LAM).

• The USNO catalogue to cover the regions far away from the principal targets and not covered by the dedicated photometry (more than 10,000,000 stars); under the resp. of OMP

• Specific catalogues identifying various types of stars; under the resp. of W. Weiss (U. of Vienna)

The Entry Star Database contains all the potentiel targets located in the COROT field of view – centre and anticentre directions - for both main scientific objectives, asteroseismology and extra-solar planet search, as well as for exploratory and additional programmes.

These data will be used for the core programme (long runs), the exploratory programmes (short runs) and the additional programmes in the exoplanet fields.

The objective is to simulate the field of view of the Detectors

In order to choose the « best » targets to fullfil the scientific goals of COROT and provide the « best » schedule of the observations over the instrument operational lifetime.

COROTSKY OVERVIEW

CorotSky provides functions to explore the Corot Entry Star Database in order to optimize the targets selection in accordance with the scientific programmes.

It takes into account the mission and instrument constraints to build observation blocks.

STEP 0 Selection of the principal

target or specific sky region

STEP 1 & 2Positionning of the detectors

on the sky Selection of candidate targets

STEP 3 Definition of windows around

the selected targets Selection of operation mode

(draft version)

STEP 3

(not available)

Compare two observation blocks

Identify a good position for the detectors

Propose a list af candidate targets

Assign a priority level to each target

Select sets of stars for the « EXOBASKET »

Assign windows and masks around selected targets

Improve the selection to optimize further the observation

Choose SCAO stars

Check mission constraints
