Outline of Final Research Achievements

We contributed to Hitomi (ASTRO-H) the integration, tests on ground, launch and operation in orbit, and achieved to the world's first astronomic observation with a X-ray microcalorimeter. We took the lead of timing calibration of the X-ray microcalorimeter and established to below 50 μs of the relative timing accuracy.
Although we lost the satellite in March 2016 unfortunately, we worked on systematic study of black holes using the data archive of Suzaku satellite. Then we found a degradation of time assignment of X-ray data in the Suzaku archive. We investigated and resolved the cause of degradation. We also developed a correction method of the degradation and success to improvement of the time assignment accuracy from about 180 ms to 1 ms.
