Outline of Final Research Achievements

We developed the search system for the night sky which cleared up partially in the whole sky image.
We have developed software for identification of stars using the SAO-J2000 catalogue. This software calculates the projection coefficient using star location on image and equatorial coordinate in catalogue. We used free statistical software R for calculate. It's possible to look for any stars on the image using the projection coefficient.
A whole sky image was divided into a lot of small areas. The weather in a small area was judged by looking for star on image using projection coefficient. The weather of every small area was recorded in a data base, searched for the sky which cleared up. We searched for this data base and looked for the part where the sky cleared up. We built a search system for the sky which cleared up partially.
