Abstract
We are developing three 1.6m optical telescopes and 18k by 18k mosaic CCD cameras. These telescopes will be installed and operated at three southern astronomical sites in Chile, South Africa, and Australia for the Korea Microlensing Telescope Network (KMTNet) project. The main scientific goal of the project is to discover earth-like extrasolar planets using the gravitational microlensing technique. To achieve the goal, each telescope at three sites will continuously monitor the specific region of Galactic bulge with 2.5 minute cadence for five years. Assuming 12 hour observation in maximum for a night, the amount of 200GB file space is required for one-night observations at each observatory. If we consider the whole project period and the data processing procedure, a few PB class data storage, high-speed network, and high performance computers are essential. In this paper, we introduce the KMTNet data management plan that handles gigantic data; observation data collecting, image calibration, data reduction pipeline, database archiving, and backup.
