Graphical Models
################

A graphical model is useful to visualize how the BEAST is structured and works.
See Gordon et al. (2016, ApJ, 826, 104, <http://adsabs.harvard.edu/abs/2016ApJ...826..104G>)
for more details on the BEAST.

Math version

*******************************
Graphical Model of Output Files
*******************************

This visualizes how BEAST runs create files when using either (a) subgrids or
(b) source density (SD) splitting.  To visualize the use of both, replace each
SED subgrid branch with an instance of the SD file tree.


Subgrids
