Archive 2.0 Release Notes

• Update to data content, including more complete information on the number of stars in a system.
• TICv8 asymmetric uncertainties handled properly.
• Null references are properly attributed.
• Stellar spectra columns updated to reflect proper published planet-star solutions.
• Overall general improvements on the content based upon continued data validation.
• Numerous bug fixes to graphical interface, including:
  
  • Correct filtering and sorting on date and character columns.
  • Updates to the columns shown by default.
• Update to TAP service to include the Gaia ID (already included in the interactive display).

• Various bug fixes
• Expanded and updated data content, including Gaia IDs, improved stellar multiplicity reporting, and improved detection flag reporting

• Combined data from Confirmed Planets and Extended Planet Data tables.
• Each row contains planet, stellar and system (TESS Input Catalog) properties.
• All solutions for confirmed exoplanet systems are now available in a single table, including Kepler, K2, and TESS candidate solutions.
• The new table also provides a nearly complete identification of published stellar companions in confirmed planetary systems.
• We've added measurements of projected and true planet obliquities.
• The table contains a summary of data sets available in the archive for a given system.

• pl_angsep
• pl_angseperr1 (positive uncertainty)
• pl_angseperr2 (negative uncertainty)
• pl_angseplim (limit)
• pl_angsep_reflink (reference)

• Update to include stellar parameters that were not published as part of the planetary solutions, providing a more complete view of the properties of the host stars.

• Update to data content, including more complete information on the number of stars in a system
• TICv8 asymmetric uncertainties handled properly.
• Null references are properly attributed.
• Stellar spectra columns updated to reflect proper published planet-star solutions.
• Planetary Systems Composite Parameters population has improved population of parameters.
• Overall general improvements on the content based upon continued data validation.
• Numerous bug fixes to graphical interface, including:
  
  • Correct filtering and sorting on date and character columns.
  • Updates to the columns shown by default.
• Update to TAP service to include the Gaia ID (already included in the interactive display).

• Added host star chemical abundances for a set of 10 elements from the Hypatia Catalog to the Stellar Parameters section.

• Added over 5,000 TESS Objects of Interest (TOIs) to new or existing pages to help identify systems with candidate planets for follow-up investigation.
• Systems with known confirmed planets now display companion TOIs on their System Overview page (e.g., HD 23472)
• New System Overview pages have been created for TOIs that are not part of a known planetary system (e.g., TOI-1812)

• Implemented overviews for candidate-only systems (e.g., KOI-753, EPIC 201127519).
• Services and interfaces that link to overviews default to new overviews, e.g., interactive tables and the Explore the Archive search on the home page.

• Improved visualization of multi-star systems.
• More complete support for Ancillary Data associated within a system.
• Updates to the color schemes, highlighting, and labeling.

• Summarized system architecture, data and graphics at the top of the page for quick reference, including flags for planets that are refuted or considered controversial. (See example)
• A special Exoplanet Archive Notes section for additional information about the system, such as whether one of its planets had been refuted and then reinstated.
• Color-coded solutions show all planet parameters associated with a given set of stellar parameters. (See example)
• Collapsible and expandable sections allow users to customize their view of the available data.
• Flexible design supports various types of system architectures.
• A Bibliography section lists all published literature references included in the archive, with links to the papers in ADS. (See example)
