Resumen:
In this work, we improve the chemical abundance - integrated colourcalibration presented in Forte, Faifer & Geisler, 2007 (FFG07 hereafter)using a new (g-i) vs. (C-T1) colours calibration obtained from M87. Us-ing this calibration and better values of the reddening for the galacticglobulars, we found that a quadratic calibration is still enough to repre-sent the observational data, as in FFG07.
