1.1 About the Multi-wavelength Data Analysis System

The Astronomy Data Center (ADC) is operating the Multi-wavelength Data Analysis System (MDAS) which is an open-use computing system. MDAS is constructed to analyze astronomy data at various wavelengths. There are over one hundred pieces of software and it supports data reduction and analysis of astronomy data observed by various telescopes.

MDAS consists of computers and its peripherals. The computers are classified into interactive data analysis servers, batch processing data analysis servers, and the MDAS terminals. Users access an interactive data analysis server with SSH connection, and they can analyze data or submit jobs into a batch processing data analysis server from the interactive data analysis server. The MDAS terminals located in the Subaru building open-use room and ALMA building room 101 on the NAOJ Mitaka campus can be used for connecting to the interactive data analysis servers.

MDAS is a computing system for “analytic researches of astronomical observation data”. For those who want to perform calculations related to the simulation astronomy, please use computing systems offered by Center for Computational Astrophysics (http://www.cfca.nao.ac.jp).
