Abstract:
TAROT (Telescope a Action Rapide pour les Objets Transitoires) is a
robotic observatory designed to observe very early optical transients
of gamma-ray bursts (GRBs). As GRBs do not often occur, we use TAROT
for various other celestial targets spread over the sky. For every
field observed by TAROT, we computed the magnitudes of every star.
From this work, we found 1175 new variable stars brighter than 17mag.
We selected the best variable star candidates and compiled them in the
TSVSC1 (TAROT Suspected Variable Star Catalog, ver. 1), which also
contains Fourier-series coefficients that fit the light curves.
Description:
TAROT is a robotic observatory located at the Calern Observatory
(43.7522° latitude north, 6.92389° longitude east, 1270m
altitude). The telescope diameter is 25cm, and the focal length is
85cm. Optical quality is achieved by an optical doublet corrector
placed at the Newtonian focus. A filter wheel allows us to acquire
images through standard B, V, R, and I photometric bands. An
additional position (hereafter referred to as the C filter) is
provided by a neutral glass filter (Schott WG280).

0 = no problem
1 = biased by a neighboor
2 = blended

6 = the object is saturated and linked to another one
8 = border
6 = badpix
≥32 = memory
Only data with flag<8 are used.
