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
    B_EROS_ and R_EROS_ magnitude, the number of star N_star_B, N_star_R
    found in the superpixel, the magnitude B_EROS_DAO and R_EROS_DAO
    estimated with DAOPHOT, and when available the cross-identifications
    with previous catalogue.
