Program Interface: Downloading Images
IRSA offers several program interfaces for images. A brief description of each is provided below, along with links to detailed instructions and examples.
Simple Image Access (SIA)
SIA is a VO-compliant method of searching IRSA's holdings for images that satisfy a variety of possible query constraints (e.g. position, wave band). IRSA has a few SIA services, but new users are encouraged to use the first in the list below.
Additional Program-Friendly Image Services
In addition to the VO-compliant services listed above, IRSA also offers additional APIs for searching images. If possible, users are encouraged to use VO-compliant protocols.
- Image and Spectrum Server (Atlas) API: Search for images based on the dataset and spatial constraints.
- Cutouts API: Retrieve subsets of original images housed by IRSA, based upon the dataset, seearch position, and size of requested image.
- Finder Chart API: The functionality of IRSA's Finder Chart tool available from the command line.
