IRSA Services

Scanpi A tool for visualizing, plotting, and averaging calibrated IRAS survey scans.
HIRES HIRES is a powerful tool for studying morphology and for separating confused sources. It uses the Maximum Correlation Method to produce IRAS images with better than nominal resolution.
General Catalog Search Access available catalogs.
IRAS FSC Download the IRAS Faint Source Catalog v2.0
IRAS PSC Download the IRAS Point Source Catalog v2.1
ISSA Custom Image Server Retrieve single images from the IRAS Sky Survey Atlas, overlaid with Point Source and Faint Source Catalog information
The IRAS Sky Survey Atlas Use Atlas to retrieve multiple FITS images from ISSA, covering a large area.
ISSA Cutouts Use IRSA's Image Cutouts Service to generate small "cutout" FITS (and JPEG) images from the IRAS Sky Survey Atlas image collection.
Improved Reprocessing of the IRAS Survey (IRIS) Use Atlas to retrieve images from the IRIS
IRIS Cutouts Use IRSA's Image Cutouts Service to generate small "cutout" FITS (and JPEG) images from the IRIS image collection.
IGA Image Server High-resolution images of the galactic plane and regions in Orion, Taurus-Auriga, and around Rho Ophiuchus (retrieves single image closest to input location)
The IRAS Galaxy Atlas (IGA) (using Atlas) Use Atlas to retrieve multiple images from the IGA covering a large area
IGA Cutouts Use IRSA's Image Cutouts Service to generate small "cutout" FITS (and JPEG) images from the IRAS Galaxy Atlas image collection.
The Extended IRAS Galaxy Atlas (EIGA) (using Atlas) Use Atlas to retrieve images from the EIGA
EIGA Cutouts Use IRSA's Image Cutouts Service to generate small "cutout" FITS (and JPEG) images from the Extended IRAS Galaxy Atlas image collection.
The Mid-Infrared Galaxy Atlas (MIGA) (using Atlas) Use Atlas to retrieve images from the MIGA
MIGA Cutouts Use IRSA's Image Cutouts Service to generate small "cutout" FITS (and JPEG) images from the Mid-Infrared Galaxy Atlas image collection.
Dust Extinction Service An interactive service that uses the maps of Schlegel, Finkbeiner and Davis to return extinction along the line of sight through the Galaxy. Returns image cutouts, and supports upload of lists of sources.
