Photometric precision
WebOct 12, 2024 · From what I've read, (e.g. Arne's discussion of QHY600) binning often reduces the dynamic range of a camera. For example, if the well is 100,000 e- per pixel, the binned 2x2 pixel is still 100,000 rather than 400000. As a result, binning reduces dynamic range and means that faint targets cannot be imaged that perhaps could be imaged in 1x1 mode. WebPhotometric Precision. The requirements on photometric precision are captured in three, top-level science requirements (see this link).A noise budget was developed during the early phases of the mission to keep track of the photometric precision that could be expected in CHEOPS light curves, given the detailed design of the misison.
