Foreground of GRBs from AKARI FIS data
  A significant number of the parameters of a gamma-ray burst (GRB) and its
host galaxy are calculated from the afterglow. There are various methods
obtaining extinction values for the necessary correction for galactic
foreground. These are: galaxy counts, from HI 21 cm surveys, from spectroscopic
measurements and colors of nearby Galactic stars, or using extinction maps
calculated from infrared surveys towards the GRB. We demonstrate that AKARI
Far-Infrared Surveyor sky surface brightness maps are useful uncovering the
fine structure of the galactic foreground of GRBs. Galactic cirrus structures
of a number of GRBs are calculated with a 2 arcminute resolution, and the
results are compared to that of other methods.
