Description:
The 91-92 EROS-1 data set has been used to select Long Timescale and
Long Period Variables (LT&LPV). We choose to perform a selection of
variable objects as comprehensive as possible, independent of
periodicity and of their position on the colour magnitude diagram, and
produce a catalogue of 632 variable objects.
Table 2 provides the parameters of the variable objects detected in
this paper. They are sorted in order of increasing right ascension.
The columns contains the name of the variable including the RA,DEC
(J2000.0) coordinates, the number of the chip and (x,y) position, the
blending flags (PhiC/Phi0)B, (PhiC/Phi0)R in both colours, the
BEROS and REROS magnitude, the number of star NstarB, NstarR
found in the superpixel, the magnitude BEROSDAO and REROSDAO
estimated with DAOPHOT, and when available the cross-identifications
with previous catalogue.
