The Arecibo Legacy Fast ALFA extragalactic HI survey uses the Arecibo multibeam receiver to survey 7000 square degrees of high galactic latitude sky. Utilizing the high sensitivity of Arecibo, the survey will detect over 20000 HI sources in the local universe. The survey products include catalogs with extracted measurements and HI parameters, as well as integrated HI spectral profiles. The survey is currently served by NED.

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 Chandra Source Catalog (CSC) includes information about X-ray
sources detected in observations obtained using the Chandra X-ray Observatory.
Release 2.0 of the catalog includes 317,167 point, compact, and extended
sources detected in ACIS and HRC-I imaging observations released
publicly prior to the end of 2014.
Observed source positions and multi-band count rates are reported, as
well as numerous derived spatial, photometric, spectral, and temporal
calibrated source properties that may be compared with data obtained
by other telescopes. Each record includes the best estimates of the
properties of a source based on data extracted from all observations
in which the source was detected.
The Chandra Source Catalog is extracted from the CXC"s Chandra Data
Archive (CDA). The CXC should be acknowledged as the source of Chandra data.
