Spectral Format Plots

Approximate wavelength coverage and calibration line locations for each combination of detector, optical element, and central wavelength, can be found in the table below. Available but unsupported modes are indicated in parenthesis.
Note: These plots are to be used as guidelines only. Both air and vacuum wavelengths were used to make them. Vacuum wavelengths are used in the STIS pipeline. Please refer to the NIST Atomic Spectra Database if you don't find what you need here.
