Summary of variability analysis.

ID Npts χred2 Fvar (%) K-S p-value Classification
RS17 135 1.18 1.32 0.041 Marginal candidate
RS23 110 1.05 0.95 0.152 Non-variable
RS24 128 1.42 2.15 0.002 Variable

RS33 142 1.59 3.41 0.0001 Confirmed variable

Notes. The columns, from left to right, are: ID of the RS corresponding to the VVV source; number of data points after the cleaning procedure (σerr < 0.25); reduced chi-squared (χ2/d.o.f.), where a value significantly greater than 1 indicates a departure from the constant model; fractional variability amplitude, representing the percentage of intrinsic flux variation after subtracting instrumental noise; p-value from the Kolmogorov-Smirnov test, values lower than 0.05 indicate that the magnitude distribution is statistically inconsistent with a constant source; final classification based on the triple-criterion consensus.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
