IRSF :InfraRed Survey Facility (IRSF) is located at Sutherland, South Africa and the survey project started since Nov. 2000 in the near infrared (J, H, Ks) bands. IRSF/Sirius :SIRIUS is a near infrared simultaneous three-band camera, and it is now mounted on the IRSF 1.4 m telescope in Sutherland, South Africa. It was developed at Nagoya Univ. and NAOJ.id:IRSF/Sirius.a |
