A test of SDSS aperture corrections using integral-field spectroscopy

Green, Andrew W; Glazebrook, Karl; Gilbank, David; McGregor, Peter; Damjanov, Ivana; Abraham, R G; Sharp, Rob


Corrections for fibre aperture losses in modern surveys such as the Sloan Digital Sky Survey are at the foundation of statistical studies of galaxy properties, yet these corrections are not well understood. We compare direct measurements of the total (aperture-free) H α-based star formation rate from integral-field spectroscopy with Brinchmann et al. and Gilbank et al. derived estimates of the star formation rate from fibre-aperture spectroscopy for the same z ≃ 0.07 star-forming galaxies drawn...[Show more]
