Resumen:
We report the development of a suitable set of transforming equations to convert the JHK VISTA photometric system (used in the VVV survey) to the widely used 2MASS photometric system. Our transformation equations have been calculated for each of 145 VVV Galactic disk fields; covering a large portion of Fourth Galactic Quadrant (295 l 350 and -2 b 2 ). Several constraints were used to extract the best sources in both systems to improve the photometric quality of the transformations.
