SFR catalogue

Summary

This catalogue contains star formation rate estimates for > 250000 galaxies from the DR2 obtained as described in Brinchmann, J. et al 2004, in press for MNRAS, "The physical properties of star-forming galaxies in the low-redshift Universe ". Please pay attention to the cautions before using the catalogue

About the catalogue

The catalogue contains all galaxies we have examined in the DR2 and contains 261054 entries in the same order as the emission line catalogue It is thus a super-set of the galaxies used in Brinchmann et al (2004).

This means that the user must show some caution in using the catalogue. In particular it is not advisable to use any SFRs measured for galaxies that do not have a stellar mass >10^5 in the stellar mass catalogue - because of the way SFRs are estimated for AGNs and Composites this would leave you with a biased sample. This leaves 211864 galaxies with estimates of SFR within the fibre and a total of 210705 with estimates of total SFRs (the two numbers are not equal because a few galaxies have problematic photometry)

In some cases the aperture corrections do fail. These have not been removed from this catalogue as it may be useful to know about them. They can almost always be indentified as galaxies where the mode and average estimate of the SFR differ by more than a factor of 20.

The cosmology used for all below is h=0.7, omega_M=0.3 and omega_L=0.7.

As discussed by Brinchmann et al (2004) we use the full likelihood distributions of the SFRs in our calculations, but for compactness we have here summarised these into medians, 2.5, 16, 84 and 97.5 percentiles as well as the mode and average of the distributions. This suffices for most applications. If you want access to the full likelihoods, get in touch with jarle at astro.up.pt.
