Please explain XX μm-selected galaxies

  1. Mar 3, 2014 #1
    Hi all,

    I'm hoping a pretty simple question. When I read about researchers working on galaxy surveys, they often state they're working on "XX-band selected galaxies". For example, D.J.B. Smith et al. performed analysis on a large number of 250μm-selected galaxies at z < 0.5.

    Is this as simple as it sounds - that they selected only galaxies that were detected with their 250μm instrument?

    Along the same lines, I've seen a few "mass selected galaxies" as well. So I'm assuming that the researcher has selected a pool of galaxies using wavelength (above example) or mass (this example) as the criteria.

    Can anyone confirm?
