CLASH 4.5 Micron Catalog: Hubble and Spitzer Observations of 25 Galaxy Clusters

The CLASH 4.5 micron Catalog contains data from the Cluster Lensing And Supernova survey with Hubble (CLASH) Multi-Cycle Treasury program. It includes Hubble Space Telescope multiwavelength observations and Spitzer IRAC data for 25 massive galaxy clusters, completed in 2013. The dataset is provided by the National Aeronautics and Space Administration and includes associated catalogs and gravitational lens models.

Use Cases

• Analyzing galaxy cluster properties based on Hubble Space Telescope multiwavelength observations.
• Studying gravitational lensing effects using the provided lens models.
• Investigating infrared galaxy properties based on Spitzer IRAC Channels 1 and 2 data.
• Conducting multi-instrument analysis using combined Hubble and Spitzer observations.

Strengths

• Observations from 25 massive galaxy clusters provide a substantial sample for analysis.
• Data combines multiwavelength observations from the Hubble Space Telescope and infrared data from Spitzer.
• Includes associated gravitational lens models, which are a key product of the survey.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection after download.
