The TAROT Suspected Variable Star Catalog contains a compilation of optical
light curves of periodic variable stars found in TAROT 2004-2006 images.
These stars are not known in the 07/2006 edition of AAVSO database .
Download the paper. In this paper you will find details
Light curves are stored in one ASCII file per star. These files can be downloaded
via hyperlinks after displaying the catalog. Light curves files are constitued
by a header followed by data. You can download
an archive containing all light curves.
Light curve filenames
TN : Means TAROT North.
N222212012 : Index of the hierachical triangular mesh (HTM) on the celestial
sphere where is the star.
9 : The 9th star in the HTM
67 : ASCII code of the filter (67=C)
2 : Camera identification (see paper)
NAME = TN-N222212012-9 (designation of the star)
RA = 109.988132 (right ascension)
DEC = 30.501096 (declination)
EQUINOX = J2000.0 (equinox)
FILTER = C (filter)
CAMERANO = 2 (# of camera: 1 or 2)
TAROT = CALERN (TAROT station name)
MEAN = 11.583593 (mean of observed magnitudes)
SIGMA = 0.190831 (standard deviation of observed magnitudes)
AMPLITUDE = 3.069301 (total amplitude of observed magnitudes)
CRITVAR = 0.087235 (criterium of variability)
PERIOD = 0.57837500000 (best period calculated)
PERIODMI= 0.040000 (lowest period tried)

col 1 : UTC julian day of observation (mid exposure)
col 2 : magnitude compared to R USNO-A2 mag.
col 3 : uncertainties of magnitude (1 sigma)
col 4 : Sextractor flag
Sextractor flag interpretation:
+1=biased by a neighboor,
If flag=6, the object is saturated and linked to another one.
Only data with flag<8 are used.
Symbols in a light curve are :
. red dot : Sextractor flag = 0 and the measurement fills in the (fitted light curve +/- sigma/2) envelope
. green dot : Sextractor flag = 0 and the measurement fills out the (fitted light curve +/- sigma/2) envelope
+ black cross : Sextractor flag > 0
Foreach variable, three figures are available : the folded light curve with the automaticaly found period, the non-phased
light curve and the folded light curve with the manualy determined period.
Tools to plot data
Matlab function plottsvsc.m is easy to use. Example
