Some of the posters, some of the codes

I used to read ADASS posters in part to find new codes to register. I still do that, but it’s harder these days, for reasons that make me very happy: many of the codes are already in the ASCL! Here is a sampling from a quick and definitely not thorough perusal of posters.

CIGALE [ascl:1111.004] and LePHARE [ascl:1108.009]

PySALT [ascl:1207.010]

SoFiA [ascl:1412.001]

Splotch [ascl: 1103.005]

TOPCAT [ascl:1101.010]

Vissage [ascl:1402.001]

It’s lovely to see ADASS folks I’ve met before, and lovely to see codes I already know. It’s also great to meet new people and run across new codes, and I’ll be highlighting some of the new codes added as a result of this ADASS in a future blog post.

Suggest a change or addition to a record

Have you found an error in an ASCL entry? Is there a paper using your code you’d like to add? Would you like to specify right in an ASCL entry how your code should be cited?

We have added a “Suggest a change or addition” link to every code entry in the ASCL. This link brings up a form that is similar to the Submissions form and allows you to not only request changes to fields currently displayed, but also enter information for fields we are considering adding.

For example, we would like to disambiguate the URLs for refereed papers into those that describe a code and those that use a code; we’d also like to add categories to make searching for codes easier.

Something that’s been on our wish list for a while is a “see also” feature, one that identifies, for a particular code, codes having a similar function or that someone looking at that code would likely be interested in, too. All we need to do this are the data!

Last update: July 20, 2021

Which journals have citations to ASCL entries…

… and which journals have the most?

I had software citations on my mind all last week, as the 3rd Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3) was held last Monday and Tuesday in Boulder, CO, and I spent a good bit of my time there in the work group for Hacking the credit and citation ecosystem (making it work, or work better, for software). This made me curious as to which journals have citations to ASCL entries, and which have the most citations to ASCL entries. I was pretty sure I knew the answer to the latter, but it’s always good to test what one knows. So I went looking, and this what I found…

These three journals and arXiv hold 84% of citations to ASCL entries:

Monthly Notices of the Royal Astronomical Society
The Astrophysical Journal
ArXiv e-prints
Astronomy and Astrophysics

Other publications with citations to the ASCL include:

The Astronomical Journal
Astronomy and Computing
The Astrophysical Journal Supplement Series
Computational Astrophysics and Cosmology
Computer Physics Communications
Galaxies
Icarus
Journal of Cosmology and Astro-Particle Physics
Journal of Physics Conference Series

Journal of Physics G Nuclear Physics
The Messenger
Physical Review C
Physical Review D
Physical Review Letters
Physics Uspekhi
Publications of the Astronomical Society of Japan
Publications of the Astronomical Society of the Pacific
Revista Mexicana de Astronomia y Astrofisica

Proceedings, too, including:

18th European White Dwarf Workshop
19th European Workshop on White Dwarfs
Astronomical Society of India Conference Series
Asymmetrical Planetary Nebulae VI Conference

EAS Publications Series
IAU Symposium
SF2A-2014: Proceedings of the Annual meeting of the French Society of Astronomy and Astrophysics
Society of Photo-Optical Instrumentation Engineers (SPIE) Conference Series

I appreciate ADS all over again for making it possible to compile this information so quickly.

August 2015 additions to the ASCL

Ten codes were added to the ASCL in August 2015:

Change to the Code Record page

From feedback we received about the “Ref” field, we’ve relabeled that field to lessen the confusion about the article link(s) in the Code Record. What had appeared is:

What now appears is:

We supply a link, too, to a page that explains what the Website, Appears in, and Bibcode fields are, and hope this makes things clearer.

If you have suggestions for the ASCL, please feel free to post them here or email editor@ascl.net. Thank you!

The “Ref” field in an ASCL entry

ASCL entries include a field called “Ref,” for “refereed.” As the ASCL indexes codes used in research, this field contains at least one link to a research article which describes a code or in which the code was used.

Screen capture showing Site and Ref fields in an ASCL entry

The information in the Ref field is used by ADS to link papers and the codes they use, making it easy for someone reading an article to find the code(s) used in that research. You can find these associations in the “Associated Articles” section of an ADS entry.

In the first image below, which is a screen clip from an ADS entry, the Source Software link brings up the ASCL entry for a code used in the article; in the second image, the Paper 1 link brings up a paper that used the code:

Some papers have several links in the Ref field:

These are papers we found while researching a code or were entered by a code author when submitting code to the ASCL. Associating article entries with entries for the codes used in those articles makes finding the software used in the research easier. And though software is increasingly cited (in a variety of ways), it isn’t always, so using the Ref/Associated Articles links can help a code author demonstrate the impact of a particular software package.

I know the ASCL is missing many of these associations; ADS and the ASCL would like to improve this linkage. If you have ideas on how to do this, please post them here, or send them to editor@ascl.net. Thanks!
