News & Announcements
UDON has restarted.
Due to expiration of the software licence and support, we stopped operation of our DARTS Lab services UDON in the end of March 2014. We have re-started UDON on a new platform. Now UDON can handle ASCA data in addition to Suzaku. The service is still experimental, so please let us know if you found any problems. (Sep 9, 2014)

A convinient web-tool "UDON" (Universe via DARTS ON-line) is back on-ine, with which you can specify a region to extracta and display X-ray light-curve and spectrum. The new UDON can handle ASCA data in addition to Suzaku. Please try samples first. Alternatively, on the search page, you can specify the satellite, and search for sources by name or observation sequence number. (2014 Oct.)
