Can someone estimate how sensitive a spectrometer has to be in order to measure the velocity spectra of Io through a 0.7m focal length refractor telescope (radius 70mm) of during optimal conditions?

A spectrometer sensitivity refers to the ability of a spectrometer to detect and measure the smallest changes in light intensity or wavelength. It is a crucial factor in determining the accuracy and precision of a spectrometer's measurements.
Spectrometer sensitivity is typically measured in terms of the minimum detectable signal, which is the smallest change in light intensity or wavelength that the spectrometer can reliably detect. It can also be measured in terms of the spectrometer's noise level or signal-to-noise ratio.
The sensitivity of a spectrometer can be affected by various factors, including the quality of its optical components, the design of its detector, the wavelength range it covers, and the level of noise in the environment. Additionally, the sensitivity may also vary depending on the type of light being measured (e.g. UV, visible, or infrared) and the specific application of the spectrometer.
The sensitivity of a spectrometer is important because it directly impacts the accuracy and precision of the measurements it produces. A spectrometer with high sensitivity will be able to detect smaller changes in light intensity or wavelength, resulting in more precise and reliable data. This is especially critical in fields such as spectroscopy, where even small variations in light can provide valuable information about the properties of a material.
There are several ways to improve the sensitivity of a spectrometer, including using higher quality optical components, optimizing the design of the detector, and reducing the level of noise in the environment. Additionally, choosing a spectrometer with a wider wavelength range can also improve sensitivity as it allows for the detection of a broader range of light. Regular maintenance and calibration can also help ensure that a spectrometer maintains its sensitivity over time.
