COMICS high-resolution Q-band spectroscopy
The high-resolution Q-band grating provides a resolution of 5300
(0.50'' slit) and a dispersion of 0.00058 um/pixel. Spectroscopy
can only be performed where narrow-band filters are available and is, at
present, limited to the 16.9-17.1 um region. The spectrum is dispersed
onto the 3rd of the COMICS spectrograph's 5 detectors.
The point-source sensitivity of the QH grating varies with
wavelength and is shown in the following figure (1 sigma for
1 second of on-source integration time per pixel).
