WebSep 18, 2024 · The Nyquist theorem is often used as a basis to choose "optimal" pixel sizes for a sensor in deep sky imaging - but it is not appropriate for two main reasons: 1) It ignores the fact that it isn't a single image being captured and instead it is a stack of aligned images where errors occur on the scale of the pixels, and 2) Nyquist is about ... There are two different definitions of resolution and resolving power in mass spectrometry. The IUPAC definition for resolution in mass spectrometry is Where a larger resolution indicates a better separation of peaks. This definition is used in a number of mass spectrometry texts. This use is also implied by the term "high-resolution mass spectrometry."
