uranography

Description

Documentation available at https://uranography.lsst.io

uranography is a collection of tools for making plots on the celestial sphere with bokeh. It is primarily intended for use in interactive environments such as jupyter notebooks or dashboards.

It supports a handful of map projections, and interactive tools that adjust them in ways that simulate traditional tools used in astronomy: the Lambert azimutal equal area projection simulates a planisphere, and the othrogrophic projection simulates an armillary sphere.

The uranography module includes tools to produce:

• bokeh transforms that apply the map projection in the client.
• projections of healpix and healsparse arrays.
• graticules in equatorial coordinates (R.A. and declination),
• graticules in horizon coordinates (altitude and azimuth),
• the ecliptic plane,
• the horizon (or circles of any other altitude),
• circles of a sphere (great or small circes) with arbitrary centers and radii, or arcs of such circles beginning and ending at arbitrary bearings from the center.
• the galactic plane, and
• stars from the Yale Bright Star Catalog.

These methods add bokeh glyphs, data sources, and renderer models with standard or manually assigned assigned names to an instance of bokeh.plotting.Figure, so they can be selected by name and adjusted and refined using the standard bokeh API.
