Starburst99 Test
Download and installation
Starburst99 source code is available from http://www.stsci.edu/science/starburst99/. This is fortran code. As well as a unix version there is a version of the code converted for use on Linux boxes (thanks to Jeremy Yates) - this is the version which i have compiled and run on a Gentoo/Linux system (Gentoo 2004.2, kernel 2.4.25).
The code comes as a tarball with full instructions for installation at http://www.stsci.edu/science/starburst99/docs/code.html
Just a couple of things that I had to alter compared to the setup instructions:
- in the file go_galaxy_linux I had to alter the 'time' command from /usr/bin/time
- ensure that you do a 'chmod +x save_output' on that file.
Input files
To construct the default model I used the standard input file - standard.input1.
In terms of output files, standard.spectrum1 shows the galaxy spectral energy distribution, as measured at a monotonically increasing series of time steps. This figure shows an example SED at one of the time steps (0.98E+08) (this plot generated through the starburst web site at http://www.stsci.edu/science/starburst99/docs/graphs/showgraph.html)
ELAIS data for comparison
The analysis that Mark Allen has made in his notes on the Pegase tests hold here. The ELAIS input catalogue is manipulated with a series of IDL routines, which then produce a SED file for each object in the catalogue. These can be read into Specview.
The starburst output files are in flux units erg/s/A - as for Pegase. Thus - for direct comparison to the SED's of the observed objects the distances of these must be known
Distance from statistical redshifts
The distances to the ELAIS objects can be determined from a photometric redshift analysis. This then enables the flux in the model to be scaled to this distance for direct comparison with the observed flux points. Some intermediate manipulation is required - but a routine to automate this would be widely useful
