The Spitzer Deep, Wide-Field Survey (SDWFS) is a four-epoch infrared survey covering 10 square degrees in the Boötes field, conducted using the IRAC instrument on the Spitzer Space Telescope. It consists of 20 band-matched catalogs providing Vega magnitudes at 3.6, 4.5, 5.8, and 8 microns, with source coordinates aligned to 2MASS positions. The data was produced by the National Aeronautics and Space Administration as a Spitzer Cycle 4 Legacy project.
A 1990s-era high-density catalog of stellar positions and proper motions compiled to provide a consistent celestial reference system. The Smithsonian Astrophysical Observatory and U.S. Naval Observatory compiled 1,643,783 input positions from over a dozen source catalogs, reducing them to the FK4 system. It is divided into two parts, with Part 1 containing 78% of stars with more reliable positions and proper motions.
Western Australia's offshore Perth Basin contains calcareous nannofossil assemblages from the Challenger No. 1 well, above the 780m level. The dataset, provided by Geoscience Australia, revises the age of the Challenger Formation type section and identifies three major disconformities. It compares the section's completeness to nearby Deep Sea Drilling Project sites.
The Spitzer Deep Wide-Field Survey (SDWFS) covers 10 square degrees in the Boötes field. It is a four-epoch infrared survey from the Spitzer Space Telescope's IRAC instrument, designed to study galaxy evolution beyond redshift 1.5 and select variable or high proper motion objects. The data was produced by NASA as a Spitzer Cycle 4 Legacy project.
Four-epoch infrared survey of 10 square degrees in the Boötes field using the Spitzer Space Telescope's IRAC instrument. The Spitzer Cycle 4 Legacy project provides 20 band-matched catalogs with Vega magnitudes at 3.6, 4.5, 5.8, and 8 microns, permitting the selection of variable and high proper motion objects. Data from the National Aeronautics and Space Administration was last updated in March 2026.
15 compact groups of galaxies observed with Chandra, Swift, and Spitzer instruments, providing data for 47 galaxies. The catalog presents total X-ray luminosities from off-nuclear point sources, along with derived star formation rates, stellar masses, and specific star formation rates. This table was created by NASA's HEASARC in May 2019 based on published astrophysical research.
11,131 bright, flat-spectrum radio sources were cataloged in the CRATES survey, which provides precise positions and spectral indices. The catalog was assembled by NASA HEASARC in 2007 from existing observations, new data, and reprocessed archival VLA and ATCA data. It contains 14,467 entries, including 762 non-detections, due to multiple 8.4-GHz counterparts for single 4.8-GHz sources.
The 2MASS 6X Merged Point Source Information Table contains merged source data from a targeted long-exposure campaign by the 2MASS observatory. It covers approximately 590 square degrees of sky across 30 regions, including deep surveys of the Large and Small Magellanic Clouds. The data was produced by NASA and provides mean positions, magnitudes, uncertainties, and confirmation statistics for sources detected multiple times.
Four-epoch infrared survey of 10 square degrees in the Boötes field, permitting the selection of variable and high proper motion objects over timescales of years. The Spitzer Cycle 4 Legacy project delivers 20 band-matched catalogs with Vega magnitudes for four IRAC wavelengths. Its large survey volume is sensitive to galaxies out to z ~ 3 with reduced cosmic variance impact.

The Boötes field, covering 10 square degrees, was surveyed by the Spitzer Space Telescope's IRAC instrument across four epochs. This dataset consists of 20 band-matched catalogs reporting Vega magnitudes in four infrared bands, with source coordinates aligned to 2MASS positions. It was produced by NASA as a Spitzer Cycle 4 Legacy project to study galaxy evolution and variable objects.
A four-epoch infrared survey of 10 square degrees in the Boötes field, conducted using the IRAC instrument on the Spitzer Space Telescope. The Spitzer Deep, Wide-Field Survey (SDWFS) provides band-matched catalogs for four epochs and a total coadd, reporting Vega magnitudes in four IRAC bands. The data was produced by the National Aeronautics and Space Administration as a Spitzer Cycle 4 Legacy project.
Geoscience Australia Data provides palynological analysis results from the Oakvale-1 corehole in the western Murray Basin, South Australia. The dataset contains diverse and well-preserved assemblages of spores, pollen, and dinoflagellate cysts from the marine Oligocene-Miocene Geera Clay and Renmark Group. A quantitative zonation based on major pollen taxa frequencies has been statistically calculated for the sequence.
242.5 KB Excel file from Karolina Cernovska, last updated May 22, 2026. Additional file 7 compares breakpoints associated with chromothripsis across a cohort of chronic lymphocytic leukemia patients.
79.7 KB Excel file compares cytogenetic banding analysis records with advanced genomic methods across a cohort of chronic lymphocytic leukemia patients. Karolina Cernovska published this supplementary data on figshare under a CC-BY-4.0 license. The dataset was last updated on May 22, 2026.
Dinoflagellate species diagnostic of the Late Miocene-Early Pliocene Bookpurnong beds and older Murray Group correlatives. The dataset likely contains stratigraphic records from the central west Murray Basin, Australia. It is hosted by the Australian Ocean Data Network.
Nine simulated microwave brightness temperature channels at frequencies from 0.4 to 2.0 GHz for the potential ESA CryoRad mission. The 4.8 GB dataset contains geophysical fields and simulated brightness temperatures for the Arctic on April 8th, 2024, generated by Josephine Juul using the SMRT model and DMI inputs. Each NetCDF file represents one full satellite orbit, covering a swath width of approximately 160 km.
Three tropical tidal creeks in Darwin Harbour were studied to compare nutrient transformation under different sewage loads. Buffalo Creek, receiving the largest sewage inputs, showed benthic nutrient fluxes more than an order of magnitude higher than the other creeks. This dataset likely contains measurements of water quality, sediment composition, benthic and pelagic metabolism, and benthic nutrient and gas fluxes.
A catalog of 424 radio sources detected near 283 unassociated gamma-ray sources from the Fermi 2FGL Catalog. The data includes positions, flux density estimates at 5 and 9 GHz, and spectral indices for 146 sources, created by NASA HEASARC in July 2013. Observations were conducted with the Australia Telescope Compact Array targeting fields of 411 gamma-ray sources with declinations less than +10 degrees.
Nannofossil and planktic foraminiferal evidence from three marginal-marine sections in the Indo-Pacific region challenges the timing of the Oligocene-Miocene boundary. The dataset suggests the planktic foraminiferal zones N.3 and N.4 should be combined, as the first appearance of Globigerinoides quadrilobatus primordius is depth-dependent and occurs earlier in shallow settings. It proposes a buffer zone between the extinction of Sphenolithus ciperoensis and the appearance of Sphenolithus belemnos to account for transitional biostratigraphic events.
