This dataset contains a processed, resampled 2D astronomical image slice derived from observations taken at the Cerro Tololo Inter-American Observatory (CTIO). The data belongs to "The Carina Time-Series Deep Field" observing program. The images have been used for MSSR algorithm to solve stars near arrouns the Sparrow Resolution Limit. 🔭 Source & Instrumentation Telescope: CTIO 4.0-m telescope Instrument: Dark Energy Camera (DECam) Observing Program: The Carina Time-Series Deep Field Principal Investigator: P.
