    Astrid Lamberts has shared the data for her star formation rates. The files are available at her website. A description:
    The following has the data from Fig.1 in Lamberts, Garrison-Kimmel, Clausen and Hopkins 2016. It provides star formation rates (in Msun/year/Mpx^3) in 100 million year time bins, over 11 metallicity bins.

    Luis Lehner
    is a faculty member of Perimeter Institute, working on 'strong/highly dynamical gravity'. In particular, he is interested in multimessenger astronomy from compact binary mergers as well as testing General Relativity.
    Pablo Marchant
    is finishing his PhD at Bonn University working with Norbert Langer on the modeling of massive binary stars. Moving out for a Postdoc on Northwestern later this year.

    As of Aug 4, 2016: Though all models for black hole binaries may be created equal (except those inferior ones proposed by our competitors), we hope that observational data will soon make them decidedly unequal. We hold these truths to be self-evident, at least after much hard thought and fine tuning, with the indicated caveats:
    If LIGO finds M_1>30Msun binary black holes with a mass ratio 0.2<q<0.5, then they are not a result of chemically homogeneous evolution of isolated binaries (i.e. in vacuum, no star cluster exchanges, triples or AGN disks).
    ...
    the only allowed loophole wouldcould be results
    If the spins of the black holes are both aligned with the orbital angular momentum, we all agree not to publish any papers proposing that the system was formed by dynamical interactions in a star cluster.
    ...
    IMFs or mass-dependent large kickspeculiar natal kick velocities scaling inversely with mass are invoked.
    If LIGO correlations with galaxy positions indicate that the typical BBH mergers are correlated with L* spiral galaxies, then the BBH mergers are not a result of Z<1/10 solar chemically homogeneous evolution, if it is confirmed that most low Z stars are currently in low Z environments. [NOT GENERALLY APPROVED]
    If one or both black hole spins are always aligned with the orbital angular momentum, then dynamically (cluster exchange) formed binaries do not contribute significantly to the rate of BBH merger.

    ...
    If no luminous red supergiants of >45Msun are found in galaxies of SMC or lower metal abundance, the standard (inhomogeneous, common-envelope) model for formation of 30+30Msun BBH will be abandoned. [Radius vs Red vs Yellow vs Blue, and numbers to be investigated]
    If LIGO observes a BBH that has an eccentricity greater than e ~ 10^{-2} when it enters the LIGO band, then dynamical formation will be accepted as the origin.
