COROTEXLOG - CoRoT Stellar Targets for Exoplanet Detection Observation Log
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: asteroseismology (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 12 of CoRoT N2 data. 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 stars observed by CoRoT in its exoplanet detection program. A few percent 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. Each entry in this table corresponds 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 channel code flag, where a value of 0 means monochromatic results are presented, and of 1 means 3-channel results.
The size of the associated file, in bytes.
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].
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].
A 9-digit unique identifier for the CoRoT target [corotid].
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.
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].
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].
The CoRoT target window identification. For the Exo channel, this can be from 0 to 8191 [win_id].
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?].
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.
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.
The Galactic Longitude of the target.
The Galactic Latitude of the target.
The contamination factor for the target [contfact].
The exposure time in seconds for the individual samples, either 32 or 512, indicating if the series is oversampled or not. A value 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].
