Query: IVOA Recommendation: Simple Image Access Specification Version 1.0   This specification defines a protocol for retrieving image data from a
variety of astronomical image repositories through a uniform interface. The
interface is meant to be reasonably simple to implement by service providers. A
query defining a rectangular region on the sky is used to query for candidate
images. The service returns a list of candidate images formatted as a VOTable.
For each candidate image an access reference URL may be used to retrieve the
image. Images may be returned in a variety of formats including FITS and
various graphics formats. Referenced images are often computed on the fly,
e.g., as cutouts from larger images.
