Advisor: Dr. Massimo Ricotti

Interface with Cloudy Photoionization Code data and RAMSES-RT Simulation
data to create galaxy images and spectra in nebular emission lines.

|                       output from many time slices.
|   |-- linelists/ : Cloudy grid run-generated line list data.
|   |   |       Contains flux for each line under specific gas parameters.
|   |   |       Note: Some parameter combinations may be nonphysical and thus
|   |   |       unused.

The Merlin is a small species of falcon from the Northern Hemisphere.
The naming of this package is inspired by the Merlin's exceptionally sharp
eyesight; we generate observational diagnostics from simulated distant,
high-redshift galaxies. Birds are a bellwether of environmental decline;
populations are down nearly 3 billion birds since 1970. Please consider
supporting/adopting local efforts to safeguard birds, their migration,
and their habitats.
