"AKARI/IRC Pointed Observation Images (Phase 1&2)" is available on DARTS
False colour images from AKARI/IRC observations. From left to right;
NGC 6946 (OBSID 1400620, Blue:Green:Red=3:7:15 micron),
IC 10 (1700216, 3:7:11),
NGC 104 (1700001, 7:11:15),
and North Ecliptic Region (5121023, 2:4:7)。
Each image is 10x10 arcmin^2.
The figure shows pointing positions in the Galactic coordinates of the ~4000 observations (Red: ~3000 photometric, Blue: ~1000 spectroscopic).
AKARI is Japan's first dedicated infrared astronomical satellite launched on February 22, 2006. AKARI carried out numerous pointing observations as well as all-sky surveys, with high sensitivity, spatial resolution, and wide wavelength.
There were three observation periods. In phase 1 and 2 the telescope and science instruments were fully operated in the cryogenic temperature by mechanical cryocooler and liquid helium, while only an instrument for near-infrared wavelengths was observed in Phase 3 using the cryocooler. The InfraRed Camera (IRC) onboard AKARI performed about 4000 pointed observations (~3000 imaging and ~1000 spectroscopic) during Phase 1 and 2. An imaging observation by IRC covers 10x10 arcmin field of view in 9 photometric bands from 9 to 26 micrometers at the maximum.
"AKARI/IRC Pointed Observation Images (Phase 1&2)" is the processed images taken with the AKARI/IRC during Phase 1 and 2. This contains calibrated images of each wavelength, corresponding dark frames, etc. They are packaged by each pointing observation. There are 3,944 data packages.
The data have been provided from the , and transferred to DARTS for permanent archive now on.
