AKARI Far-infrared All-Sky Survey Maps[Last update: 13 Mar 2017]
- Change Log
Description of data files, file formats, contents, and caveats for the users are presented. Users of the data are strongly recommended to read this note prior to playing with the data.
Following papers describes details of the AKARI Far-infrared All-Sky Survey Maps, data processing and calibration, and basic performance of the catalogues.
- Image Query Service
- Beam Profile (PSF_NSWSWL.zip)
The FIS beam profiles are created for the shortest three bands (N60, WIDE-S, and WIDE-L) by stacking images of standard stars as the same manner with Arimatsu et al. 2014 PASJ 66 47. The profile for N160 band is not available due to low S/N ratio for standard stars. However, since the characteristics of point sources at WIDE-L and N160 bands are similar, you can assume that the N160 PSF is the same with WIDE-L one. Note that since the PSFs are constructed by stacking images of standard stars, its accuracy and universality are not guaranteed, such as similarity of the PSF shape at different sky position (or dependency to the number of scans).
- Region List (region_list.txt)
This is a list of map region ID and its center coordinate in J2000.
The use of this catalogue for the scientific analysis should follow the guidelines for publication.
