  An improved version of the identification stellar sources module in the
quasi-automatic SACAMAN code is presented, which allows to obtain YZJHKs-VVV
magnitudes for a set of predefined objects. The procedure uses a proximity
algorithm $\simeq$ 70 less time-consuming than the previous method of
successive and counting approximation. This code is being applied to the study
of variability of carbon stars belonging to the Galactic Bulge.
