ADC_Keywords: Observatory log ; Stars, variable Mission_Name: CoRoT Description: CoRoT (Convection, Rotation and planetary Transit) is a space experiment with a double objective: study the stellar interiors (asterosismology), and search for extrasolar planets. The satellite was launched on 27 December 2006, and delivers light curves with an unprecedented resolution in both time (32s resolution in uninterrupted observations of 30 or 150 days) and photometry (better than a millimag). Two regions of 1.4x2.8° are covered (CoRoT's "eyes"): one toward the galactic center (around 06:50+00), the other toward the anticenter (around 18:50+00) CoRoT has two main scientific programs: asterosismology (observations of stellar oscillations) targeted to a small set of stars observed without interruption during one run, summarized in file "astero.dat"; and exoplanet detection by the occultation or transit method, summarized in file "exo.dat". The data correspond to the public release 3.2 of CoRoT N2 data (19-Jun-2009). More details on the CoRoT N2 data may be found in the "DescriptionN2v1.2.pdf" documentation file. File Summary:

Note (1): the variability classification results from an automatic treatment of the light curve, and is quite uncertain. The classes are defined in Debosscher et al. 2009A&A...506..519D, as follows: ACT = presence of Activity BCEP = β-Cephei stars BE = Variable Be-stars CLCEP = Classical Cepheids (δ-Cep) CP = Chemically peculiar stars DMCEP = Double-mode Cepheids DSCUT = δ-Scuti stars E1L = (?undefined?) E1R = (?undefined?) E2L = (?undefined?) E2R = (?undefined?) ECL = Eclipsing binaries (all types) ELL = Ellipsoidal variables FUORI = FU-Ori stars GDOR = γ-Doradus stars HAEBE = Herbig Ae/Be stars LAPV = Low-amplitude periodic variables LBOO = λ-Bootis variables LBV = Luminous Blue variables MIRA = Mira variables MISC = Miscellanous variable (undecided) PTCEP = Population II Cepheids PVSG = Periodically variable supergiants ROT = Rotational modulation RRAB = RR-Lyrae stars, subtype ab RRC = RR-Lyrae stars, subtype c RRD = Double-mode RR-Lyrae stars RVTAU = RV-Tauri stars SDBV = Pulsating subdwarf B-stars SPB = Slowly pulsating B-stars SPDS = Short-period δ-Scuti variables SR = Semi-regular variables SXPHE = SX-Phe stars TTAU = T-Tauri stars WR = Wolf-Rayet stars XB = X-ray binaries
Global Notes: Note (G1): the run is coded "tRann", where t = 'L' (long), 'S' (short), or 'I' (initial) a = 'c' (center) or 'a' (anticenter), and nn = the run number. Examples: LRa01, SRc01, etc.
