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 👀

This looks super cool! It seems more like an interactive "widget" to me, rather than a "dashboard". Is there more that I'm not seeing?

There's vsini and RV for high resolution spectra, and it can also accept input data for data-model overlays for by-eye fitting. It has some other information presented to deal with un-evenly spaced grids. So yeah, semi-dashboard, semi-widget?

Designed to be used in Jupyter Notebooks, yes?

(so happy to see you using specutils!!)

One of the conceivable extensions would be to show an instananeous view of which grid point is selected, perhaps color-coded with some goodness-of-fit metric. That change would make the tool more like a human-in-the-loop data-fitting dashboard. Some folks have requested a feature like that, but there's no currently plan to implement it, mostly because it's hard to visualize the grid over all of its ~4 or 5 dimensions. A corner plot could work, but is bulky. In such a view the 2D projections would show dots for each available grid point, sliced from the larger say 5D grid.

Yes, it only works in Jupyter notebooks right now, and it runs Python callbacks behind the scenes, so it's not clear how to get it onto a website.

We're using interactive Bokeh stuff for the SIMPLE Archive website. One could imagine integrating this into that. Let's talk in Toulouse!
