    74 The BPASS (Binary Population and Spectral Synthesis) stellar population synthesis models are available [http://bpass.auckland.ac.nz/index.html here]. We support importing the v2.0 grids that can be downloaded [http://bpass.auckland.ac.nz/2.html here] under the header "SEDs". The grids are available as tarballs for several different choices of the initial mass function. The tarball contains grids assuming either an instantaneous starburst of 1e6 Msol, or continuous star formation of 1 Msol/yr lasting 1e6 years. Each of these grids has separate models for single-star and binary-star evolution. Grids are available for a range of metallicities ranging from Z=0.001 to 0.040. The first step is to download one or more of the tarballs from the BPASS website. Next you run the script [http://data.nublado.org/stars/convert_bpassv2.pl convert_bpassv2.pl] (make sure that the file has execute permission) as is shown below:

We support importing the v2.0 grids that can be downloaded [http://bpass.auckland.ac.nz/2.html here] under the header "SEDs", as well as the v2.1 grids that are available [http://bpass.auckland.ac.nz/8.html here]. The grids are available as tarballs for several different choices of the initial mass function. The tarball contains grids assuming either an instantaneous starburst of 1e6 Msol, or continuous star formation of 1 Msol/yr lasting 1e6 years (the latter only for v2.0). Each of these grids has separate models for single-star and binary-star evolution. Grids are available for a range of metallicities ranging from Z=0.001 to 0.040 (v2.0) or Z=0.00001 to 0.040 (v2.1). The first step is to download one or more of the tarballs from the BPASS website. Next you run the script [http://data.nublado.org/stars/convert_bpassv2.x.pl convert_bpassv2.x.pl] (make sure that the file has execute permission). Below we describe the process for a BPASS v2.0 grid:

    109109The code for calculating the grids is described in [http://adsabs.harvard.edu/abs/2009MNRAS.400.1019E Eldridge & Stanway (2006)].

     111The instructions for installing a BPASS v2.1 grid are very similar:
     112{{{
     113<download BPASSv2.1_imf135_100.tar from BPASS website>
     114<download convert_bpassv2.x.pl>
     115chmod +x convert_bpassv2.x.pl
     116tar xvf BPASSv2.1_imf135_100.tar
     117cd BPASSv2.1_imf135_100
     118../convert_bpassv2.x.pl
     119}}}
     120This will create two ascii files:
     121{{{
     122BPASSv2.1_imf135_100_burst_single.ascii
     123BPASSv2.1_imf135_100_burst_binary.ascii
     124}}}
     125As was already mentioned above, continuous star formation files are no longer produced in v2.1, hence only two files are produced instead of four. The remainder of the procedure for using the ascii files is the same as above.
