The Chandra X-ray Observatory is the U.S. follow-on to the Einstein
Observatory. Chandra was formerly known as AXAF, the Advanced X-ray
Astrophysics Facility, but renamed by NASA in December, 1998.
Originally three instruments and a high-resolution mirror carried in
one spacecraft, the project was reworked in 1992 and 1993. The Chandra
spacecraft carries a high resolution mirror, two imaging detectors,
and two sets of transmission gratings. Important Chandra features are:
an order of magnitude improvement in spatial resolution, good
sensitivity from 0.1 to 10 keV, and the capability for high spectral
resolution observations over most of this range.
The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope by
combining the tens of thousands of visit-based source lists in the Hubble Legacy Archive (HLA)
into a single master catalog.
The Hubble Source Catalog (HSC) detailed search
displays an entry for each separate detection (or nondetection if nothing is found at that position)
using all the relevant Hubble observations for a given object
(i.e., different filters, detectors, separate visits).
The catalog currently contains over 100 million entries.
The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope
by combining the tens of thousands visit-based source lists in the Hubble Legacy Archive (HLA)
into a single master catalog.
The HSC Summary search displays a single row entry for each object,
as defined by a set of detections that have been cross-matched and hence are believed to be a single object.
Averaged values for magnitudes and other relevant parameters are provided.
The catalog currently contains over 16 million entries.
The Subaru Prime Focus Camera (Suprime-Cam) is a mosaic of ten 2048 x 4096 CCDs, located at the prime focus of Subaru Telescope, which covers a 34' x 27' field of view with a pixel scale of 0.20''. This service provides access to the JVO Subaru Suprime-Cam mosaic image archive. The purpose of this archive is to provide quick look images taken by Subaru/Suprime-Cam. Those images were processed by a pipeline developed by JVO.
