AN EXTENSION OF A RELIABLE WAVELENGTH COVERAGE OF THE AKARI NG GRISM MODE

다국어 초록 (Multilingual Abstract)

The Infrared Camera onboard the \textit{AKARI} satellite carried out spectroscopic observations with a grism mode named \textit{NG}, whose wavelength coverage was 2.5--5.0~$\mu$m.
We reinvestigate the current flux calibration for the \textit{NG} grism mode, with which calculated flux density implausibly decreases at 4.9~$\mu$m especially for red objects due to the second-order light contamination.
We perform a new spectral response calibration using blue and red standard objects simultaneously.
New response curves which contain both the first- and second-order light are able to separate each contribution consistently and useful for studies of red objects such as CO ro-vibrational absorption in active galactic nuclei.
