galSpecExtraSPECTRO Estimated physical parameters for all galaxies in the MPA-JHU spectroscopic catalogue.
The estimates for stellar mass are derived using the methodology described in Kauffmann et al (2003), applied to photometric data as described in Salim et al (2007). The star formation rates are derived as discussed in Brinchmann et al (2004), but the aperture corrections are done by estimating SFRs from SED fits to the photometry outside the fiber following the methodology in Salim et al (2007).
