Abstract: The Solar Ultraviolet Imaging Telescope (SUIT) on board Aditya-L1 makes full-disk observations of the Sun in eleven filters within the 200-400 nm wavelength band. The spacecraft maintains a halo orbit around the Sun-Earth L1 point, enabling SUIT to take continuous observations of the solar photosphere and chromosphere. The raw data downloaded from the spacecraft is processed to generate science-ready Level-1 data, which is currently available for public use. The initial level of processing involves dark and bias corrections, flat-fielding, and stray light correction. The level 1 processing also implements the coordinate system on the image data, which is necessary for easy co-registration of SUIT images with data from other observatories. The Level-1 data is further processed to generate Level-2 data products. This stage of processing primarily includes morphological corrections, such as spot and contamination removal, spiked pixel removal, and image deconvolution for sharpening of morphological features. Additionally, the Level-2 processing toolkit will be publicly available, enabling end-users to process SUIT data with specific modules as needed. This presentation will cover the image calibration and processing of SUIT data, with a focus on generating Level 2 data products. We will also present the achieved level of correction and a quantitative account of the residual errors in the SUIT data products.
