IRSA Services
| IRAS Catalog Search | Access available IRAS catalogs. |
|---|---|
| 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. |
| 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. |
| Image Cutouts Service | An interactive service that generates small "cutout" FITS (and JPEG) images from IRSA image collections. |
Additional Data
| IRAS Catalogs | Search public IRAS catalog data, which includes access to PSC and FSC bulk downloads. |
|---|---|
| IRAS Sky Survey Atlas (ISSA) | IRSA's DCE is a generic tool for performing cone or polygon searches to find overlapping images within a dataset (including ISSA), provide interactive visualizations of these images, and optionally, catalog overlays and downloads. |
| Improved Reprocessing of the IRAS Survey (IRIS) | Use DCE to retrieve images from the IRIS |
| IRAS Galaxy Atlas (IGA) | Use DCE to retrieve multiple images from the IGA covering a large area |
| Extended IRAS Galaxy Atlas (EIGA) | Use DCE to retrieve images from the EIGA |
| Mid-Infrared Galaxy Atlas (MIGA) | Use DCE to retrieve images from the MIGA |
| The Extended Atlas of Low-resolution Spectra from the Infrared Astronomical Satellite | Use DCE to retrieve images from IRAS_LRS |
