Galactic Populations of LISA DWD Binaries

These COSMIC simulation outputs and assembled galactic populations of
    Double White Dwarf (DWD) binaries
    represent the work published by V. Delfavero et al,
    in https://arxiv.org/abs/2409.15230

The COSMIC version used in these simulations is 3.4.10

The git repository for the accompanying code which built this dataset
    will be available at https://gitlab.com/xevra/basil-cosmic
    upon the publication of our article.

Also useful is the fork of ldasoft used in this pipeline:

Please cite this work if you use the included data in a publication.

Summary
-------------------------------------------------------------------------------
Params_[MODEL].ini
    This initialization file was used for COSMIC, 
       for the runs tagged with [MODEL].

[MODEL]_[KSTAR1]_[KSTAR2]_[METALLICITY_BIN].tar.gz
    This tarball contains the outputs from one run of COSMIC,
        using Params_[MODEL].ini, for a type of binary indicated by
        [KSTAR1] and [KSTAR2] according to COSMIC syntax,
        and for the [METALLICITY_BIN]'th metallicity bin.

[MODEL]_COSMIC.hdf5
    This hdf5 database holds the DWD population outputs for all 60
        COSMIC simulations in a compressed format.
    It only holds information about binary systems at the end
        of evolution (conv, according to COSMIC syntax).
    It does not contain the evolutionary history of individual binaries
        (the bpp information, according to COSMIC syntax).

[MODEL]_m12i-000_LISA.nal.hdf5
    This hdf5 database holds the LISA "resolved" population of DWD binaries
        for a single realization of a Milky-Way-like galaxy.
    It also stores many attributes indicating assumptions and various
        population statistics.
    The "nal" extension indicates that this database contains
        truncated Gaussian likelihood models for the resolved population
        of LISA DWDs,
        which can be loaded by the gwalk code (https://gitlab.com/xevra/gwalk).
    This database can also be explored by any hdf5 library (such as h5py).

[MODEL]_m12i-000_LISA.hdf5
    This hdf5 database holds all of the LISA-band binaries (f_GW > 10^-4 Hz)
        for a single galaxy realization.

[MODEL]_m12i-000_LISA.txt.gz
    This text file stores the inputs for ldasoft gbfisher analysis,
        for a specific galaxy realization under assumptions
        broadly described by [MODEL]
