Version 1.1 is a validation and reproducibility release for cosmic birefringence detection. It reports highly significant, scale-dependent rotation of the linear polarization plane in the Cosmic Microwave Background derived from Planck 2018 SMICA and NILC maps over multipoles β = 500β1500. The dataset was created by Amy Condit of 22 Blue CMB Birefringence & Standing-Wave Rotation Field and last updated on 2026-06-17.
8.5Ο isotropic and 4β5Ο directional polarization rotation signals were measured in Planck 2018 SMICA and NILC component-separated polarization maps across the multipole range β = 500β1500. The analysis, conducted by Amy Condit of the 22 Blue CMB Birefringence & Standing-Wave Rotation Field, uses linearized EB estimators and a quantitative q-mask to measure rotation angles as a function of angular scale. The dataset, last updated on 2026-06-17, includes figures illustrating isotropic and directional birefringence measurements and statistical validation.

827 stars identified as variable from over 75,000 optical-wavelength light curves of guide stars used for pointing control of the Chandra X-ray Observatory. The Chandra Variable Guide Star Catalog (VGUIDE) contains 586 definite and 241 possible variable stars, with 319 believed to be new identifications, and was created by NASA HEASARC based on data from about 9 years of the mission. Variable types include eclipsing binaries, pulsating stars, and rotating stars, detected to amplitudes as low as 0.02 mag in the 4000-10000 Angstrom range.
An elliptic medium Earth orbit satellite system for Nordic/Arctic areas is proposed and investigated. The dataset includes comprehensive link budgets for VHF and S-band, along with performance analysis of user terminal antenna solutions for fixed and ship-based installations. It was authored by Terje RΓΈste and last updated on 2026-04-30.
17,969 isolated radio components cataloged from a high-resolution 1.4-GHz survey covering 92 square degrees of the Sloan Digital Sky Survey (SDSS) Stripe 82 region. Observations were conducted with the Very Large Array (VLA) primarily in the A configuration during the 2007-2009 cycles by the National Radio Astronomy Observatory (NRAO). The HEASARC created this table from the survey in August 2013.
Australian Ocean Data Network provides a dataset on dinoflagellate cysts used for stratigraphic correlation. The data likely contains species lists that distinguish Late Miocene-Early Pliocene Bookpurnong beds from older Oligocene-Middle Miocene formations in the central west Murray Basin. The dataset was last updated on 2026-06-05.
Plazi provides digitized taxonomic treatments based on the 2015 journal article 'Three new earthworm species of the genus Polypheretima Michaelsen, 1934 (Oligochaeta: Megascolecidae) from Vietnam'. The data originates from the journal Zootaxa, volume 3905, issue 4, pages 593-600. The dataset is published under an Open Access (green) license.

Decay spectroscopy data originates from the November 2014 campaign of experiment IS471 on francium isotopes. The data was collected using the CRIS experimental setup at the CERN ISOLDE facility. The dataset is authored by John Billowes of the University of Manchester and is available under an Open Access license.
A pilot study dataset from a randomized controlled trial investigating the effects of a Halliwick-based aquatic exercise program on children with autism spectrum disorder. The dataset includes assessments for 12 children across four time points, measuring social and motor skills using scales like ATEC, CARS, CSIS, and HAAR. The data was uploaded by Yu Liu to figshare in May 2026 under a CC-BY-4.0 license.
A six-satellite constellation launched in 2006 provides global GPS radio occultation measurements for deriving planetary boundary layer height. The PBL height is calculated as the altitude where the vertical gradient of atmospheric refractivity is at a minimum, indicating the transition from the free troposphere. This seasonal average climatology product supersedes previous versions and is based on data from COSMIC/FORMOSAT-3, TerraSAR-X, KOMPSAT-5, and PAZ satellites.
5,890 radio sources above a 40 mJy flux-density limit were cataloged in the Australia Telescope 20-GHz Survey (AT20G), a blind survey covering the sky south of declination 0 degrees from 2004 to 2008. The catalog, created by NASA HEASARC in 2010, includes total intensity and polarisation measurements at 20 GHz for all sources, with most sources south of -15 degrees also having flux-density measurements at 5 and 8 GHz. The authors report a catalog reliability of essentially 100% due to visual inspection of each source.
Lord Howe Province sea water temperature data collected by one or more temperature loggers deployed at the Comets Hole site. The Australian Ocean Data Network gathered this data from March 2009 to March 2019. The dataset was last updated on the platform in June 2026.
A spectral library of marine benthic habitats in oligotrophic, temperate waters. The data was collected for a PhD thesis at Murdoch University and is hosted in the Australian National Spectral Database. It covers areas near Rottnest, Marmion, and Shoalwater in Western Australia.
The VLA-VIRMOS Deep Field 20-cm Source Catalog contains 1,103 entries for 1,054 radio sources detected in a 1 square degree region centered at RA 02 26 00, Dec -04 30 00 (J2000.0).
