Saturation

  If the user provides source flux density estimates ( 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.

 
Figure: SWS grating instrumental profiles. The solid lines represent Gaussian fits. SW: laser plus continuum. LW: laser and dark current  

  
Figure: 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

  
Figure: Measured SWS grating spectral response function for SWS AOT Bands 1A and 1B. The data of Band 1A are affected by noise. Vertical lines indicate the wavelength limits of the bands

  
Figure: Measured SWS grating spectral response function for SWS AOT Bands 1D and 1E. The data of Band 1D are affected by noise

  
Figure: Measured SWS grating spectral response function for SWS AOT Bands 2A and 2B. The fringes are real

  
Figure: Measured SWS grating spectral response function for SWS AOT Bands 2C and 3A. The fringes in the data for Band 2C are real

  
Figure: Measured SWS grating spectral response function for SWS AOT Bands 3C and 3D. The fringes are real

  
Figure: Measured SWS grating spectral response function for SWS AOT Bands 3E and 4. The fringes are real
