Jy, depending on band), which are accurate within a factor of four,
than the amplifier gain setting will be such that the SWS will have no
saturation problems.

Gaussian fits. SW: laser plus continuum. LW: laser and dark current
Figure 5.2: Calculated SWS grating spectral resolution (confirmed by spot
checks) as a function of wavelength for extended sources. The spectral
orders are indicated in circles.
For point sources the resolution of SW spectra will be about a factor
two larger; for LW spectra this effect is not significant
