IRC Relative Spectral Responsivity Function (RSRF)

The following tables show the relative spectral response (RSR) curves, which take account of the photon to energy conversion of the detector quantum efficiency by multiplying by the wavelengths (FAD = Filter and Detector).

These RSRs can directly be integrated over spectra given as F_λ to obtain the in-band fluxes.

These RSRs have been prepared in collaboration with Martin Cohen and assure the common calibration of the IRC with other missions and ground-based instruments, including Subaru/COMICS, in the framework of the absolutecalibration network provided by Martin Cohen and his colleagues.

The present RSRs are prepared on the basis of the best laboratory measurements of the optical elements of the IRC
