  • 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).
