ASCL poster at AAS #229

With 1,400 codes, the Astrophysics Source Code Library (ASCL, ascl.net) is the largest indexed resource for codes used in astronomy research in existence. This free online registry was established in 1999, is indexed by Web of Science and ADS, and is citable, with citations to its entries tracked by ADS. Registering your code with the ASCL is easy with our online submissions system. Making your software available for examination shows confidence in your research and makes your research more transparent, reproducible, and falsifiable. ASCL registration allows your software to be cited on its own merits and provides a citation that is trackable and accepted by all astronomy journals and journals such as Science and Nature. Registration also allows others to find your code more easily. This presentation covers the benefits of registering astronomy research software with the ASCL.

ADASS XXVI poster: Decoupling the Archive

Decoupling the archive posterThe James Webb Space Telescope (JWST) archive will store numerous metadata for the various files that it contains: at the time of this writing a single FITS file can have up to 250 different metadata fields in the archive, most of which map to keywords in the primary header or header extensions. One of the goals of the archive design is to allow for changes to the fields stored in the database without having to change the ingest code. We have found this to be very helpful during the code development phase of the mission when the FITS file definitions are frequently changing. We also anticipate it will be advantageous during the lifetime of the mission as changes to processing will likely result in changes to the keywords but should not require changes to the ingest code. This poster describes the methods we use to decouple the archive from the ingest process.

Montage poster at ADASS 2016

We want to share some of the posters that are appearing at ADASS this week (with permission of their authors). Montage is in the ASCL; we love this poster for several reasons, but especially because it makes clear that sustainability of the software is important!
Image of paper on the software Montagle

Abstract: The Montage toolkit is finding exceptional breadth of usage, far beyond its intended application as a mosaic engine for astronomy. New uses include:
– Visualization of complex images with data overlays: e.g. as a re-projection engine integrated into the server-side architecture of a Gbit visualization system supporting investigations of 3D printing with the X3D protocol creation of sky coverage maps for missions and projects bulk creation of sub-images of multiband photometry data creation of plots in the APLPy library.
– Creation of new data products at scale: mosaics of Gemini AO images from the Gemini Multi-Conjugate Adaptive Optics System/Gemini South Adaptive Optics Imager (GEMS/GSAOI) instrument, from the VISTA VIDEO and the UKIDSS DXS surveys welding the Herschel infrared Galactic plane (Hi-GAL) far-infrared Survey into a set of large-scale mosaics, for planetarium shows at a digital as well as for research
– As a re-projection engine to support discovery of 86 Near Earth Asteroids (a U.S. congressional mandate) in the Lincoln Near-Earth Asteroid Research Program (LINEAR).
– Integration into data processing environments: integration of the 4D image cutout tool into the VO-compliant CSIRO ASKAP Science Data Archive (CASDA) as a re-projection engine for the Dark Energy Survey (DES) pipeline.
– Discovery of imaging data at scale: use of memory mapped R-tree indices to support searches for spatially extended data, in use in Spitzer and WISE image searches and in spatial and temporal searches for WISE and KOA.
It has been cited as an exemplar application for development of next generation cyber-infrastructure in 238 papers between 2014 and 2016 to date. What has enabled this broad take-up is that Montage has been built and managed as a scalable toolkit, written in C and portable across all common *nix platforms, with minimal dependencies on third-party software, such that it can be built with a simple “make” command. All the components have proven powerful general-purpose tools in their own right, even those first developed to support mosaic creation, such as discovery of images for input to the engine and for management of mosaics. We describe how Montage is managed to assure that the benefits of the architecture are retained, and how we ensure that new development is driven by the needs of the community.

ASCL poster at ADASS XXVI

ASCL poster for ADASS XXVIThe Astrophysics Source Code Library (ASCL) is a free online registry of codes used in research; it is indexed by ADS and Web of Science and has over 1300 code entries. Its entries are increasingly used to cite software; citations have been at least doubling each year since 2012, and every major astronomy journal accepts citations to the ASCL. Codes in the resource cover all aspects of astrophysics research and many programming languages are represented. In the past year, the ASCL has added dashboards for users and administrators, started minting DOIs for codes it houses, and added metadata fields requested by users. This presentation covers the ASCL’s growth in the past year and the opportunities afforded to it as one of the few domain libraries for science research codes, and will solicit ideas for new features.

AAS 227 Poster 348.01: Making your code citable with the Astrophysics Source Code Library

Image of poster on ASCL showing how it can be used to cite software and get currently untrackable DOIs tracked in ADS

The Astrophysics Source Code Library (ASCL, ascl.net) is a free online registry of codes used in astronomy research. With nearly 1,200 codes, it is the largest indexed resource for astronomy codes in existence. Established in 1999, it offers software authors a path to citation of their research codes even without publication of a paper describing the software, and offers scientists a way to find codes used in refereed publications, thus improving the transparency of the research. Citations using ASCL IDs are accepted by major astronomy journals and if formatted properly are tracked by ADS and other indexing services. The number of citations to ASCL entries increased sharply from 110 citations in January 2014 to 456 citations in September 2015. The percentage of code entries in ASCL that were cited at least once rose from 7.5% in January 2014 to 17.4% in September 2015. The ASCL’s mid-2014 infrastructure upgrade added an easy entry submission form, more flexible browsing, search capabilities, and an RSS feeder for updates. A Changes/Additions form added this past fall lets authors submit links for papers that use their codes for addition to the ASCL entry even if those papers don’t formally cite the codes, thus increasing the transparency of that research and capturing the value of their software to the community.

AAS 227 Poster 247.07: Astronomy Education and the Astrophysics Source Code Library

Image of ASCL education poster

The Astrophysics Source Code Library (ASCL) is an online registry of source codes used in refereed astrophysics research. It currently lists nearly 1,200 codes and covers all aspects of computational astrophysics. How can this resource be of use to educators and to the graduate students they mentor? The ASCL serves as a discovery tool for codes that can be used for one’s own research. Graduate students can also investigate existing codes to see how common astronomical problems are approached numerically in practice, and use these codes as benchmarks for their own solutions to these problems. Further, they can deepen their knowledge of software practices and techniques through examination of others’ codes.

ASCL at AAS 227

Posters! Sessions! Meetings! The upcoming AAS meeting in Kissimmee, Florida is shaping up to be the busiest ever! Here are the formal meeting activities the ASCL is participating in.

Special Session: Tools and Tips for Better Software (aka Pain Reduction for Code Authors)
Tuesday, January 05, 2:00 PM – 3:30 PM; Sanibel
Organizers: Astrophysics Source Code Library (ASCL)/Moore-Sloan Data Science Environment at NYU

Research in astronomy is increasingly dependent on software methods and astronomers are increasingly called upon to write, collaborate on, release, and archive research quality software, but how can these be more easily accomplished? Building on comments and questions from previous AAS special sessions, this session, organized by the Astrophysics Source Code Library (ASCL) and the Moore-Sloan Data Science Environment at NYU, explores methods for improving software by using available tools and best practices to ease the burden and increase the reward of doing so. With version control software such as git and svn and companion online sites such as GitHub and Bitbucket, documentation generators such as Doxygen and Sphinx, and Travis CI, Intern, and Jenkins available to aid in testing software, it is now far easier to write, document and test code. Presentations cover best practices, tools, and tips for managing the life cycle of software, testing software and creating documentation, managing releases, and easing software production and sharing. After the presentations, the floor will be open for discussion and questions.

The topics and panelists are:

Source code management with version control software, Kenza S. Arraki
Software testing, Adrian M. Price-Whelan
The importance of documenting code, and how you might make yourself do it, Erik J. Tollerud
Best practices for code release, G. Bruce Berriman
Community building and its impact on sustainable scientific software, Matthew Turk
What to do with a dead research code, Robert J. Nemiroff

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.
