Abstract:
We present the integrated properties of the stellar populations in the
Universidad Complutense de Madrid (UCM) Survey galaxies. Applying the
techniques described in the first paper of this series (Perez-Gonzalez
et al., 2003, Cat. J/MNRAS/338/508), we derive ages, burst masses
and metallicities of the newly formed stars in our sample galaxies.

Note (1): When the best-fitting model is different from the default models
(SB99 (Leitherer et al., 1999ApJS..123....3L 1999ApJS..123....3L) models, instantaneous
SFR, Salpeter IMF and CF00 (Charlot & Fall, 2000ApJ...539..718C 2000ApJ...539..718C)
extinction recipe), a second line is added for each galaxy with the
results obtained using the best set of input parameters (i.e. the
model fit showing the lowest C2, provided that it is below 4).
Note (2): When no code is given, the results refer to the SB99 models,
instantaneous SFR, Salpeter IMF and CF00 extinction recipe.
The others are as follows:
1 = BC99INSTSALPCF00
