Community Uptake of 'Best Practices for Data Publication in the Astronomical Literature'
Abstract
The journal article 'Best Practices for Data Publication in the Astronomical Literature' (https://scixplorer.org/abs/2022ApJS..260....5C/) was an international collaboration among major astrophysics archives and journals. Since publication, the Best Practices has been linked by leading journal publishers in their instructions for authors and has been cited in over a dozen journal articles to date. I will review highlights of the Best Practices and its uptake by the astronomical community so far and discuss persistent challenges that remain for harvesting data from the literature for NED and other astronomical archives. -----

•Best Practices for Data Publication in the Astronomical Literature (Chen et al. 2022ApJS..260….5C) •A broad-based effort led by NED, in response to growth and complexity of data published in the literature •A call to authors to publish cleaner, unambiguous, and better documented data •Addresses important FAIR principles •Strong connection to NASA’s Open Science Program: Following BPs will improve the scientific record, enhance reusability, and help streamline ingest into archives 3
FAIR Principles •F1: (Meta)data are assigned globally unique and persistent identifiers •F2: Data are described with rich metadata •A1: (Meta)data are retrievable by their identifier using a standardized communications protocol •A1.1: The protocol is open, free, and universally implementable •A1.2: The protocol allows for an authentication and authorization procedure, where necessary • I1: (Meta)data use a formal, accessible, shared, and broadly applicable language for knowledge representation • I2: (Meta)data use vocabularies that follow FAIR principles • I3: (Meta)data include qualified references to other (meta)data • R1.2: (Meta)data are associated with detailed provenance • R1.3: (Meta)data meet domain-relevant community standards 4 Findable Reusable Accessible Interoperable
Astrophysical Data Guidelines – General Rules 5 a) Define all symbols, acronyms, and abbreviations at first use. E.g., a green check mark indicates a good usage or recommendation, a red “X” is used next to a bad or confusing example, and a question mark is used when the example is ambiguous. b) Provide uncertainty and confidence level when reporting a new measurement. P = 1.23456 +/- 0.00012 days P = 1.23456 (12) days ∆P = 0.0000012 days? c) Present the appropriate number of significant figures for numerical measurements and uncertainties that match the precision of the measurements. • (RA, Dec) = (131.32134587º, 1.01243229º) accuracy of 10-8 deg or 10-5 arcsec d) Report the units for measurements, if present, and adopt commonly used ones. • Use recommendations by the IAU on units in astronomy and astrophysics (Rots et al. 2021) e) Indicate preferred values, if applicable.
6 Astrophysical Data Guidelines – Nomenclature a) Provide the complete name for each object. b) Include the “J” in names based on J2000 coordinates. c) Insert spacers between a catalog name and the identifiers within the catalog.

7 d) Distinguish between part of an object and the object itself. 3C 295 Cluster 3C 295 (when referring to the cluster) e) Do not use the same name for different objects. tau Ceti b, c, d, e, f, g, h (when b, c, d were refuted) f) Always assign a name and verify the name is unique. •Check IAU Dictionary of Nomenclature of Celestial Objects to avoid reusing existing ones. •Submit a new acronym to the IAU Designations and Nomenclature WG for review and registration. g) Keep the appropriate number of significant figures in coordinate-based names. •If coordinate designations are used, truncate the object’s position – don’t round up. E.g., for an object at 14ℎ41𝑚𝑚57𝑠𝑠.249 +09°48′59".15 XYZ J144157.24+084859.1 XYZ J144157.25+094859.2 Astrophysical Data Guidelines – Nomenclature

16 a) Provide a clear title and unambiguous labels of columns – include units b) Explain the content of each column – does “z” mean redshift or the photometric filter? c) Keep each column homogeneous. •A single column should not present measurements with different units, mix errors with limits or comments, or append flags to values d) Use clearly defined, nonnumeric representations for missing (null) values. Null or NaN (Not a Number) are recommended “-999” or “0” are not to be used as place-holders e) Accompany a machine-readable table (MRT) with a ReadMe file. Data Presentation – Tables
17 a) Provide clear caption, legend, and axis labels for each figure • Clearly indicate what different colors, symbols, and lines represent Figures should be able to stand alone without requiring much reading of the main text. b) Create the graphics with accessibility in mind • E.g., color-blind users would benefit from symbols that vary in shape in addition to colors. c) Include information for "data behind the plots“ • The original data files used to generate the figures need to be publicly available Data Presentation – Figures
18 a) Append small data sets as part of the publication •larger data sets can be supplemental files b) Deposit large or complex data at well-established data centers • Use a trusted repository that issues Digital Object Identifiers (DOIs) c) Provide a complete list of metadata •Metadata is needed to fully comprehend the data and includes aspects of the data such as the creation, standards, and quality of the data d) Include a Data Availability Statement, if required by the journal Data Archiving and Access
19 The link http://www.asiaa.sinica.edu.tw/~yychang/ca.html in a 2017 article generates the following message in 2023: 404 Not Found ==================================================================== From a 2023 article: "The Host/FRB catalogue is available at the FRB Host Database http://frbhosts.org" However, upon clicking on this link one gets "The domain Frbhosts.org may be for sale." e) Do not publish data sets at URLs lacking long-term support. • We strongly discourage the publication of URLs to personal web servers Data Archiving and Access
20 a) Cite the original references • If data were obtained from a service, acknowledge the service E.g. "We adopted a heliocentric redshift of 1.234 (Smith et al. 2012) via NED", where "Smith et al. 2012" is listed correctly in your bibliography. b) Use preferred citations by the authors •E.g. the 2MASS web page requests that you cite the canonical paper by Skrutskie et al. (2006), instead of the Explanatory Supplement. c) Provide full provenance of the data •cite all data/sources/software used d) Include all references in the bibliography - not just in footnotes e) Distinguish original data in your article and data taken from other work. •Use phrases such as "This work" to clearly identify original data in your article Citation and Credits - Literature Citations
21 a) Explicitly indicate the facility involved - make sure the name is unique b) Use standardized keywords, when possible •E.g. AAS has created keyword tags to be used with AASTeX - \facility and \facilities a) Include the facility's own statement, if available • Refer to the phrase that was in place at the time the facility was used. Citation and Credits - Facility Credits From a 2023 journal article: •“the 12 m ARO Telescope on Kitt Peak (KP12)” •“Astronomical Research Observatory” ? •“Arizona Radio Observatory”? •“Abbey Ridge Observatory”? •“Algonquin Radio Observatory”?
22 a) List the software and version used in the production of the article including: •the name of the author(s) •title of the program/source code •the code version •a permanent URL link to the code publisher Citation and Credits - Software Credits
23 a) Use DOIs to cite related content • This includes specific data sets, software, and services used • The DOI links should be included in the bibliography Citation and Credits – Digital Object Identifiers Complication: When a new version of data are delivered, a new DOI should be minted. What should be done if a small addition is made to the previously delivered data requiring small changes to documentation? •New DOI for ensemble data set? •New DOI just for the new data? •Leave the old DOI as is?
24 a) Tag articles with relevant data content keywords from the Unified Astronomy Thesaurus (UAT) • Use UAT keywords that best describe the types of data contained in the article. Data Content Keywords
