Resumen:
               We present a characterization method based on spectralcross-correlation to obtain the physical parameters of the controversialstellar aggregate ESO 442-SC04. The data used was obtained with GMOSat Gemini-South telescope. Spectral types, effective temperature, sufacegravity and metallicities parameters were determined using FXCOR tocorrelate cluster spectra with ELODIE spectral library and selecting thebest correlation matches using the Tonry and Davis Ratio (TDR). Anal-ysis of the results suggests that the stars in ESO 442-SC04 are not boundand therefore they do not constitute a physical system.
