yi-jia-li/cue: v0.1

An initial release of the nebular emission emulator Cue.

Cue is a flexible tool for interpreting nebular emission across a wide range of ionizing conditions of galaxies. It is a neural net emulator based on the Cloudy photoionization code. It does not require a specific ionizing spectrum as a source, instead approximating the ionizing spectrum with a 4-part piece-wise power-law. Along with the flexible ionizing spectra, Cue allows freedom in [O/H], [N/O], [C/O], gas density, and total ionizing photon budget.
