Reanalysis of near-infrared extragalactic background light based on the
  IRTS observation
  We reanalyze data of near-infrared background taken by Infrared Telescope in
Space (IRTS) based on up-to-date observational results of zodiacal light,
integrated star light and diffuse Galactic light. We confirm the existence of
residual isotropic emission, which is slightly lower but almost the same as
previously reported. At wavelengths longer than 2 {\mu}m, the result is fairly
consistent with the recent observation with AKARI. We also perform the same
analysis using a different zodiacal light model by Wright and detected residual
isotropic emission that is slightly lower than that based on the original
Kelsall model. Both models show the residual isotropic emission that is
significantly brighter than the integrated light of galaxies.
