This report represents echelle spectral formats (echellograms) and response functions of Infrared Camera and Spectrograph (IRCS) from zJ- to M-bands. The response function of each setting in this report includes the transmittance of atmosphere, blaze functions of echelle and cross-disperser gratings, and transmittance of the filter.

[$\blacksquare$] The infrared spectral lines shown on echellograms and response functions are as follows:
[a] OH lines (Steed & Baker, 1979)
[b] Ar lines (Rao, Humphreys, & Rank, 1966)
[c][Fe II] lines (Nussbaumer & Storey, 1988)
[d] Atomic Hydrogen lines (Hummer & Storey, 1987)
[e] Molecular Hydrogen lines (UKIRT Homepage)¹
[f] He I and He II lines (UKIRT Homepage)
[g] $^{12} C ^{16} O$ and $^{13} C ^{16} O$ bandheads (UKIRT Homepage)
[h] $^{12} C ^{16} O$ and $^{13} C ^{16} O$ fundamental (1-0) band lines 4.50 - 5.00 $\mu$m (UKIRT Homepage)
Each line group is marked with different color as indicated at lower-left corner of each echellogram.

[$\blacksquare$] Each value in `Intensity' column of tables in this report indicates as follows:

[a] Intensities in kR for OH lines (Steed & Baker, 1979)
[b] Einstein coefficients for [Fe II] lines (Nussbaumer & Storey, 1988)
[c] Relative intensities of I(line)/I(H$\beta$) for atomic Hydrogen lines(Hummer & Storey, 1987)
[d] Relative intensities of I(line)/I(1-0S(1)) at LTE (T=4000 K) for $H_2$ lines (UKIRT homepage)

[$\blacksquare$] The accuracies of `X' and `Y' columns are about $\pm$10 pixels ²

[$\blacksquare$] The atmospheric transmittance for the Mauna Kea summit was calculated from 1.0 $\mu$m to 5.5 $\mu$m by `ATRAN' program of Load (1992).

The current version of echelle simulator calculates echellograms without correction of optical abbretions. We will correct the optical abbretions for the higher fitting accuracies in the next version.
