Programs
The observation time for the KMTNet primary science, i.e., Galactic bulge monitoring, has already been allocated. The bottom figure shows the bulge observing time by red line between February 20 and October 22, which is about 46% of the total observing time, as well as the non-bulge one by blue line. The monitoring data are used for the following science cases.
1) Search for exoplanets using the microlensing method
2) Search for transiting exoplanets
3) Search for variable objects
4) Data mining in search for asteroids and comets
The non-bulge season was open to the Korean astronomical community and the following seven programs have been selected. These programs were scheduled to use the observation time of about 34% until 2019.
1) Supernova research using the KMTNet facility
2) The KMTNet Deep Ecliptic Patrol of the SOUTHern sky: The DEEP-SOUTH-survey and physical characterization of asteroids and comets
3) Deep wide-field imaging of nearby galaxies
4) Detection and physical characterization of ultra-faint Milky-Way satellite galaxies in the southern hemisphere
5) BVI,Ha photometric survey of the Magellanic Clouds
6) KMTNet Intensive Nearby southern Galaxy group Survey (KINGS)
7) Probing the vicinity of supermassive black holes with AGN variability
The other non-bulge time is used for collaboration with host countries (i.e. Chile, South Africa, and Australia) and allocated for the director/engineering time.
Policies
Similar to most survey projects, we also have internal rules and regulations for the members who use the KMTNet system for their specific sciences. The users should follow the science policy of the KMTNet project.

Policies
Similar to most survey projects, we also have internal rules and regulations for the members who use the KMTNet system for their specific sciences. The users should follow the science policy of the KMTNet project.
1) The most important regulation is related to the detection of exoplanets. Because the primary goal of the KMTNet project is to search for exoplanets, all exoplanet candidates discovered from the KMTNet data should be told to and strictly kept within the KMTNet team before being announced to outside members/community privately or publicly. The team members will examine the observation data of the planet candidates and will decide further actions. In the case of exoplanet discoveries using the microlensing method, we ask that you follow the data policies described on the webpage(https://kmtnet.kasi.re.kr/ulens/).
2) The regular proprietary period of the KMTNet data is one year. This period can be extended up to three years with the approval of the KMTNet advisory committee.
3) The papers based on the KMTNet data shall follow the guidelines for publications as below:
– All papers should include the word KMTNet in the title or abstract.
– The papers should include at least one KASI staff member as a co-author.
– The papers should cite at least one paper as a reference and include the acknowledgments specified by the KMTNet team.
