Low resolution Brown Dwarf grid tutorial and animated gif

[gully]

We should make a tutorial showing how to apply the interactive dashboards to low resolution spectra. We had previously focused on high-resolution applications, but many practitioners think at low resolution, especially for ultracool dwarfs, where high resolution had historically been difficult to obtain.

Here is a demo of the new Sonora-Bobcat ultracool dwarf dashboard illuminating some satisfying morphology as you move sliders for temperature, surface gravity, and metallicity.

This dashboard may be of-interest to folks at BDNYC (and elsewhere) @kelle @jfaherty17 👀
