ZARTH is an outreach effort of the Zwicky Transient Facility - a collaboration of 16 institutions around the world led by Caltech who pursue frontier research in time-domain astronomy. The app was mostly developed by graduate students and their senior advisors. As such, we don't have a dedicated team of developers to continuously support the app. However, we will try to do our best to keep the app up and running and as resources permit respond to your requests. Don't hesitate to contact us via our email zarth-ztf [at] caltech [dot] edu.
