Loading from Virtual Observatory#

The Virtual Observatory (VO) loader allows you to access data through VO protocols using a simple cone search.

Note

This feature is currently in development. Stay tuned for updates!

These protocols allow seamless access to astronomical data across multiple archives using standardized interfaces.

UI Access#

v0.1
Click toolbar icons to toggle different sidebars
Data Menu

Control data and subset layer order and visibility for each viewer. Toggle layer visibility, reorder layers by dragging, and manage which data appears in the viewer. 

dm = jd.viewers[viewer].data_menu

API Access#

import jdaviz as jd
jd.show()

# Using loaders API
ldr = jd.loaders['virtual observatory']
ldr.show()

ldr.source = 'M4'
...
ldr.query_archive()

Since there are many options and the exposed options depend on previous selections, the best way to write a script to write a workflow loading from astroquery is to enable API Hints, and interactively do a search in the UI and reproduce in a notebook cell:
