SAUSERO (Software to AUtomatize in a Simple Environment the Reduction of Osiris+) processes raw science frames to address noise, cosmetic defects, and pixel heterogeneity, preparing them for photometric analysis for OSIRIS+ (Gran Telescopio Canarias). Correcting these artifacts is a critical prerequisite for reliable scientific analysis. The software applies observation-specific reduction steps, ensuring optimized treatment for different data types. Developed with a focus on simplicity and efficiency, SAUSERO streamlines the reduction pipeline, enabling researchers to obtain calibrated data ready for photometric studies.
