Services
(in alphabetical order)
| Tool (click to launch) | Serves data? | Brief Description | Documentation |
|---|---|---|---|
| Application Programming Interfaces (APIs) | yes, via the APIs | This page is an introduction to all the API instructions at IRSA | Introduction |
| Atlas | yes | Atlas is our Image and Spectrum Server. Most data set pages have links to Atlas for that data set (e.g., SEIP) | Online help and List of Datasets |
| Background Model | no | This tool gives optical-to-infrared background estimates for observations from the Earth-Sun L2 Lagrangian region, the future site of the James Webb Space Telescope (JWST) and Euclid. | Help page |
| Catalog Search Tool | yes | The Catalog Search Tool (powered by Gator) enables complex searches of catalogs at IRSA. Also used "under the hood" in other tools here. | Online help (also see Video tutorials) |
| Coordinate and Object Lookup | no | Use this tool to resolve names or convert coordinates. Used "under the hood" by other tools here. | Instructions |
| Cutouts | yes | Cutouts creates subimages from original files. Standalone tool but also used "under the hood" by other tools here. | Instructions and List of Datasets |
| Data Discovery (more commonly accessed from "Search for Source" box on main IRSA page) | yes | Use Data Discovery (sometimes called Radar) to find data sets at IRSA covering your search position. | Online help (also see Video tutorials) |
| Dust Extinction | partially yes | The Galactic Dust Reddening and Extinction Service gives the foreground (Milky Way) reddening for a line of sight, returning a reddening map, the corresponding 100 micron intensity, dust temperature, statistics, and Galactic extinctions using two methods. | Summary |
| Finder Chart | yes | Finder Chart is a tool that allows cross-comparison of images from various surveys of different wavelengths and different epochs. | Online help and Known Bugs and Issues (also see Video tutorials) |
| HIRES | yes | Generate higher-resolution IRAS images with HIRES | Instructions |
| Image Mosaic Service | returns mosaic you request | Powered by Montage, this service creates science-grade mosaics from exposures. | Help; also see Montage page |
| Image Validator | no | This service checks that the syntax of a FITS file conforms to the FITS standard, and that the World Coordinate System (WCS) keywords are complete and have the correct datatype. | simple help |
| IRSA Viewer | yes | This tool enables searches of myriad datasets for images and catalogs, including interactive exploration of the data. | Online help and Known Bugs and Issues (also see Video tutorials) |
| IRTF Archive | yes | This archive contains data from the NASA Infrared Telescope Facilty (IRTF). | Online help (also see Video tutorials) |
| MOST | provides link to launch IRSA Viewer with data | The Moving Object Search Tool (MOST) can determine the orbit for a given Solar System object then find images that covered the object's predicted positions in select image datasets housed at IRSA. | Instructions |
| NASA Planck Archive | yes | This tool provides an interactive way of exploring Planck images and the most commonly used catalogs. | Online help and Known Bugs and Issues |
| PTF Image Service | yes | The Palomar Transient Factory (PTF) Image Service is the repository for all image data collected by PTF and processed by IPAC. | Online help and Known Bugs and Issues |
| Scanpi | yes | IRAS Scan Processing and Integration tool (Scanpi) is an interactive software tool for viewing, plotting, and averaging the calibrated survey scans from IRAS. | Help linked from bottom of tool |
| SOFIA Archive | yes | This archive contains data from SOFIA, the Stratospheric Observatory for Infrared Astronomy. | Online help and Known Bugs and Issues (also see Video tutorials) |
| Spitzer Heritage Archive | yes | The Spitzer Heritage Archive contains data from the Spitzer Space Telescope. | Online help and Known Bugs and Issues (also see Video tutorials and entire set of Spitzer documentation) |
| SWAS Spectrum Server | yes | The Submillimeter Wave Astronomy Satellite (SWAS) Spectrum Server contains data from SWAS. | User's Guide |
| Spitzer data analysis tools | no | The Spitzer repository contains several data analysis tools. | Spitzer data analysis tools documentation |
| Table Validator | no | This tool checks (and fixes, if possible) IPAC Table File format files. | Instructions |
| Time Series Tool | partially yes | This tool works with time series data. It will visualize images from specific epochs for ZTF, PTF, and WISE data; you can use this tool to search for periods in data from these missions or any time series data file. This tool is embedded within IRSA Viewer. | Online help and Known Bugs and Issues (also see Video tutorials) |
| WISE Image Service | yes | This tool serves image and catalog data from WISE (Wide-field Infrared Survey Explorer), NEOWISE, and NEOWISE-R. | Online help and Known Bugs and Issues (also see Video tutorials) |
| WISE/NEOWISE Coadder | returns the coadd you request | This tool enables coaddition of exposures from WISE, NEOWISE, and/or NEOWISE-R. | Instructions |
| ZTF Image Service | yes | The Zwicky Transient Factory (ZTF) Image Service is the repository for all image data collected by ZTF and processed by IPAC. | Online help and Known Bugs and Issues |
