Bisei Space Guard Center (BSGC) is an optical telescope facility in Japan, operated by JAXA. It tracks near-Earth asteroids and space debris.
DARTS provides data observed by a 25 cm telescope from 2000 to 2002 and data observed by a 1 m telescope from 2007 to 2017.
MOIRCS (Multi-Object InfraRed Camera and Spectrograph) provides wide-field imaging and long-slit / multi-object (MOS) spectroscopic capabilities in the 0.9 ~ 2.5 µm spectral range under the natural seeing condition. The 4'?~7' field of view is covered by two Hawaii-2 2048?~2048 arrays with the spatial resolution of 0.117 arcsec/pixel.

Description:
A significant fraction of the mission time of VSOP was to be dedicated to the VSOP Survey Programme of bright compact Active Galactic Nuclei (AGN) at 5 GHz, which was lead by ISAS. The VSOP Survey Sources are an unbiased dataset of 294 targets, of which 82% were successfully observed.
The Archive is formed with all files measured with ARcetri Near Infrared CAmera ( ARNICA). Each files contains (in FITS format) or a single exposure or the mean of single exposures taken at the same telescope position. The filer used can be either a Johnson broad band infrared filter (J, H, K), or a narrow band filter (see ARNICA) page for details). Most measures was acquired at the TIRGO telescope, while a smaller sample cames from the few telescopes Arnica was ported to (WHT, NOT, VATT and TNG). All frame are in FITS format and are 256x256 pixels in size. The archive contains more than 250.000 frames. Most files belongs to a compound measure (we call them "a mosaic").
DOLORES (Device Optimized for the LOw RESolution) is a focal reducer instrument installed at the Nasmyth B focus of the TNG. The detector is a 2048 x 2048 E2V 4240 Thinned back-illuminated, deep-depleted, Astro-BB coated CCD with a pixel size of 13.5 µ. The scale is 0.252 arcsec/px which yields a field of view of about 8.6 x 8.6 arcmin. The instrument allows imaging through broad and narrow band filters as well as spectroscopic observations with resolving powers between RS=~500 and RS=~6000. A multi-slit mode, based on custom masks manufactured by a dedicate cutting machine, is also available. Please note that MOS programs are bound to strict constraints on the number of masks and on the time necessary to design and manufacture them. In particular, each program can request up to a maximum of 5 masks per night and 10 masks per observing run.
