SIA compliance report for Hubble Space Telescope Press Release Image Archive

Description:
The Hubble Space Telescope Press Release Image Archive is a pointed image archive of press release images from the Hubble Space Telescope. The resource provides a conditionally compliant simple image access (SIA) interface to access the image archive. SIA 1.0 compliance is conditional because press release images, in general, do not retain specific observation parameters like observation date and spectral bandpass. The TIFF or JPEG format images are highly processed (i.e., unsuited for astronomical analysis), and may contain annotations on top of the astronomical image. All images have associated valid world coordinate system metadata. Identical images may be available in the archive with different access identifiers, different image formats, or different pixel resolutions.
