What is the Solar Data Analysis System (SDAS) @ ADC

In March 2013, the Solar Data Analysis System (SDAS) at Astronomy Data Center (ADC)/NAOJ was constructed from the data archive / analysis systems of Hinode Science Center, Nobeyama Solar Radio Observatory and Solar Observatory. The SDAS is the succeeding system of the systems operated by the observatories, and is operated by ADC and the observatories. Because the data analysis systems of the observatories are fused, all solar data of NAOJ can be analyzed on this system simultaneously.
