One of the two standardized filter sets used for BRIEF projects, SLOAN ugriz is widely used due to its distinct, low-overlap response curves and generally flexible and efficient nature.
Used to determine the quality of your image, the Full Width Half Maximum (FWHM) process is used to determine the quality of images and is of particular importance in photometric and exoplanet research work. BRIEF primarily uses the OSS Pipeline to account for the FWHM process.
The signal-to-noise ratio (SNR) characterizes the quality of a measurement and determines the ultimate performance of the system. The three primary sources of noise in a CCD imaging system are photon noise, dark noise, and read noise, all of which must be considered in the SNR calculation.
