COROTEXLOG - CoRoT Stellar Targets for Exoplanet Detection Observation Log |
HEASARC Archive |
The CoRoT satellite was launched on 27 December 2006, and delivers light curves with an unprecedented resolution in both the time domain (32s resolution in uninterrupted observations of 30 or 150 days) and photometry (better than a millimagnitude). Two regions of 1.4 x 2.8 degrees are covered (referred to as CoRoT's "eyes"): one roughly toward the galactic center (around RA = 18:50, Dec = +00),the other the anticenter (around RA = 06:50, Dec = +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 the file ftp://cdsarc.u-strasbg.fr/pub/cats/B/corot/astero.dat and not included in the present table, and exoplanet detection by the occultation or transit method, with the list of targets as summarized herein.
The data in this table correspond to the public release 10 of CoRoT N2 data (2012-04-19). More details on the CoRoT N2 data may be found in the documentation file http://idoc-corotn2-public.ias.u-psud.fr/jsp/doc/DescriptionN2v1.3.pdf.
This table contains information on 116,820 stars observed by CoRoT in its exoplanet detection program. 3300 of these stars have 2 entries since they were observed in different windows (as specified by the corot_window_id parameter) in a subsequent observing run to the initial run in which they were observed. There are thus a total number of 120,120 entries in this table corresponding to the unique specification of target and corot_window_id, each with a link to its associated N2 data products.
The original names of the parameters in this table, as given in the CoRoT mission documentation, are given in square brackets at the end of the parameter descriptions listed below.

The CoRoT data products generation date and time
[crea_dat].
CoRoT_Lc_File
The directory structure and file name of the light curve file
containing the time series data and available as a remote data product for
this entry.

The version of the pipeline processing that
generated the data products [pipe_ver].
N2_Version_Num
The version number of the N2 primary scientific data
products [n2_ver].
CoRoT_Channel_Code
The CoRoT channel code flag, where a value of 0 means
monochromatic results are presented, and of 1 means 3-channel results.
CoRoT_File_Size
The size of the associated file, in bytes.
Time
The UT date and time of the start time for the use of a given
window for the target specified by the corot_id parameter [t_start_win].
End_Time
The UT date and time of the end time for the use of a given
window for the target specified by the corot_id parameter [t_end_win].
CoRoT_ID
A 9-digit unique identifier for the CoRoT target [corotid].
Name
The CoRoT target designation using the 'CoRoT' prefix
and the corot_id parameter value, as recommended by the CDS Dictionary of
Nomenclature of Celestial Objects.
CoRoT_Run_Code
The CoRoT run code for the target and observation,
coded as 'tRpnn', where t = 'L' (long), 'S' (short), or 'I' (initial), 'R'
stands for run, p = 'c' (Galactic center pointing) or 'a' (anticenter
pointing), and nn = the run number; for example, 'LRa01', 'SRc01', etc
[run_code].
CoRoT_Halfccd_ID
The reference for the half CCD from which the product
originates, where, for example, 'E1R' refers to the right ('R') CCD number
1 of the Exo-planet ('E') channel [hlfccdid].
CoRoT_Window_ID
The CoRoT target window identification. For the Exo
channel, this can be from 0 to 8191 [win_id].
Target_Mag
The magnitude of the target. The HEASARC does not know for
certain in which band this is measured, but it is probably the V band
[magnit_v?].
RA
The Right Ascension of the target in the selected equinox. This was
given in J2000 decimal degrees to a precision of 10-5 degrees in the
original table.
Dec
The Declination of the target in the selected equinox. This was
given in J2000 decimal degrees to a precision of 10-5 degrees in the
original table.
LII
The Galactic Longitude of the target.
BII
The Galactic Latitude of the target.
Contam_Factor
The contamination factor for the target [contfact].
Exposure
The exposure time in seconds for the individual samples, either
32 or 512, indicating if the series is oversampled or not. A avlue of -1
indicates that during the run a change occurred in the sampling, i.e., it
either shifted from 512 to 32 s or the converse) [exptime].
