slcomp is a compilation of strong gravitational lensing systems. It provides tabular data, raw FITS image cutouts, and processed color images from multiple wide-field surveys. This dataset is intended for astrophysical research, including statistical studies, preparation for upcoming surveys (e.g., Rubin LSST), machine learning model training, and planning follow-up observations.
