Description
Reduced images of gravitational lenses captured by the Hubble Space Telescope across three specific observation programs (16773, 17307, and 15867) form the core of this collection. Produced by Courtney Watson and updated through March 2026, the data includes observations using WFC3 and ACS filters alongside mock RGB composites.
Use Cases
Morphological analysis of gravitational lenses using WFC3 F200LP and F140W filter images
Visual inspection of lens candidates through mock RGB color composites
Cross-instrument calibration between ACS F606W and WFC3 filters for lensing targets
Strengths
Includes multi-filter coverage (WFC3 F200LP, F140W and ACS F606W)
Provides mock RGB color images for multi-filter targets
Aggregates data from three distinct HST programs (16773, 17307, 15867)
Limitations
Program 17307 data collection was still ongoing as of early 2026
Unknown total record count or file size
Missing metadata regarding specific target coordinates or redshift values in the provided description
