MAXI has two major objectives, 1) to issue rapid alerts of new X-ray novae/transients into astronomers worldwide and 2) to acquire long-term allsky X-ray data. Thanks to the good network connection between the ISS and the ground station, we can obtain 70% of MAXI data through the real-time communication path. We built a ground system (referred as“ MAXI-DB”) to handle real-time data efficiently; with the MAXI-DB and the alert system we issued 29150 rapid alerts in the three years since MAXI started observation. It is crucial to provide MAXI data to scientists all over the world, because MAXI data includes rich information. The MAXI data has been released to public step by step. Daily data products including images, light curves and energy spectra for 29300 pre-registered X-ray sources have been archived on the MAXI web site (http://maxi.riken.jp/top). Since the MAXI data taken by the slit-scan observation includes complex information on all-sky X-ray sources, it is not easy to collect data for a given source quickly on demand. We thus developed the MAXI on-demand archive system which sort all event data in orders of the sky region and the time. The new archive system is confirmed to process data for any celestial source 29100 times faster than the former system.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
