  • AJ & ApJ are owned by the AAS
  • Graph is just a power law: f(x)=axk+o(xk)
  • Rethink X axis in terms of “intellectual complexity” or intellectual investment
  • Tabular, image data in several formats
    MRT/Vizier, VOT, FITS - Ad hoc submissions by authors, since 1993
    E.g. 10.1086/512773 (MRT), 10.1086/382244 (FITS)
    “Data behind the figures”
    Simple plots: 1D & 2D, spectra, CM diagrams, etc., easy to serialize in tabular form - So we can apply current procedures
  • Three main outcomes
  • Ssp astro data 2014 may

    1. 1. SSP, May 2014 Data publishing from the AAS perspective A bit of history Our current point of view Data sharing attitudes of astronomers
    2. 2. SSP, May 2014 American Astronomical Society Largest organization of research astronomers, 100+ yrs, 6500+ members The Astronomical Journal, 150+ yrs, IF = 5.0  2013: 330 articles, 4375 pages The Astrophysical Journal, 100+ yrs, IF = 6.7  Letters (IF = 6.3), Supplement (IF = 16.2)  2013: 3731 articles, 45150 pages
    3. 3. SSP, May 2014 AAS Heritage of Publishing Data  AAS founded the Astrophysical Journal Supplement in 1954 to publish the “data-rich” papers of the day.  The move to electronic publishing (as the version of record) ended the era of extensive typeset tables  AAS journals currently accept machine readable tables, FITS format, movies, and other VO- compatible formats.
    4. 4. SSP, May 2014
    5. 5. SSP, May 2014 Long Tail of Science Data DataVolume Number of datasets Large data sets at facility archives are well-tended Moderate- to small-sized data sets are at risk Graphic from B. Heidorn
    6. 6. SSP, May 2014 Long Tail of Science Data DataVolume Intellectual complexity? Large data sets at facility archives are well-tended Moderate- to small-sized data sets are at risk Graphic from B. Heidorn MAST IRSA CXC SDSS Journals, CDS, et al.
    7. 7. SSP, May 2014 Data and linkages to data Data in the journal Data outside the journal  Link resources together: object names (SIMBAD), data set names (ADS et al.) Nurture partnerships with important partners  ADS, CDS, VO, et al.  DataCite: TIB, BL, CDL, et al.  CrossRef, Portico, other scholarly community
    8. 8. SSP, May 2014 MRTs in ApJ and ApJS 0 50 100 150 200 250 2004 2005 2006 2007 2008 2009 2010 2011 2012 ApJ ApJS Data in the journal Current AAS data formats  Machine readable tables (MRTs)  Figure sets and extended figures  Data behind figures (DbF)  FITS files  Animations  Source code
    9. 9. SSP, May 2014 Data behind the figures
    10. 10. SSP, May 2014 Understanding what we have and what people want  Survey figure types in the journals  AAS author survey as part of a 2012 NSF data grant •.
    11. 11. SSP, May 2014 AAS/AIP data access project 1. Journals will extend the methods for providing access to data objects 2. Survey community attitudes about data sharing and re- use 3. Engage community in discussions about formats and metadata Responds to various calls for digital data curation and sharing  EC: Riding the Wave (2010)  UK/RIN: Collaborative Yet Independent (2011)  US NSB: Digital Research Data Sharing and Management (2011)
    12. 12. SSP, May 2014 Data sharing/attitudes survey Conducted by AIP SRC 12/12 – 1/13  With NSF support ~1000 respondents in astrophysics and plasma physics (68% response) Two main themes  Use: requests, receipts, re-use  Sharing: inquiries, deliveries  Recently (past 2 yrs) and future expectation
    13. 13. SSP, May 2014 Data sharing survey 62% shared in last two years 58% expect to share in next two years  Plus 28% who said “possibly” 60% have requested data in last two years 68% expect to request in next two years  Plus 23% who said “possibly” Astronomers generally have no problems with data sharing
    14. 14. SSP, May 2014 1) 60% have requested data in last two years How data was obtained 0 10 20 30 40 50 60 70 Directly from author Large data repository Publishing Journal Affiliated institution Other % How data was used 0 10 20 30 40 50 60 70 80 90 Explore new questions Integrate sources Replicate work Other % 2) 3) AAS & AIP data sharing survey: Highlights regarding using data
