Resumen:
We present a new algorithm ''Fast Integrated Spectra Analyzer'' (FISA) that is suitablefor a fast age and reddening determination of small angular diameter stellar clusters byusing their integrated spectra and the available template spectrum libraries. Thisalgorithm and its implementation helps to reach fast astrophysical results incomparatively shorter times. In this study, we describe in detail the numerical algorithmemployed and show a few examples of its application. We publish a release of thecode. So far, the integrated spectroscopy of open clusters has been successfully usedto determine their ages and reddenings, including both Galactic and Magellanic Cloudsstellar clusters. We also present a brief review of the integrated spectroscopictechnique applied to the study of open clusters as well as the basic assumptions tojustify its use.
