JS9 bespoke

This demo originally used specific FITS sample data that this site no longer ships, so it displays the bundled example.fits.gz instead. Restore the original data/ files to see it as intended.

JS9 Demo: an HTML interface (instead of a menubar)

The menubar is only one way to interface with JS9. Web designers can create their own graphical inteface, using standard HTML elements that call the JS9 Public API to perform the appropriate actions.

Choose a JS9 menu action to perform:
zoom:
scale:
cmap:
regions:
analysis:
