    • HERITAGE LMC Band-Matched Catalog

    Metadata Updated: September 19, 2025

    Observations from the HERschel Inventory of the Agents of Galaxy Evolution (HERITAGE) have been used to identify dusty populations of sources in the Large and Small Magellanic Clouds (LMC and SMC).The study used the HERITAGE catalogs of point sources from both the Photodetector Array Camera and Spectrometer (PACS; 100 and 160 microns) and Spectral and Photometric Imaging Receiver (SPIRE; 250, 350, and 500 microns) cameras. These catalogs are matched to each other to create a Herschel band-merged catalog and then further matched to archival Spitzer IRAC and MIPS catalogs from the Spitzer Surveying the Agents of Galaxy Evolution (SAGE) and SAGE-SMC surveys to create single mid- to far-infrared (far-IR) point source catalogs that span the wavelength range from 3.6 to 500 microns. There are 35,322 unique sources in the LMC and 7503 in the SMC.
