StatCodes is a metasite with links to over 200 sites providing free on-line codes implementing statistical methods that may be useful to astronomers. Methods include time series analysis, multivariate analysis, censored and truncated data, nonparametric statistics, correlation and regression, Bayesian methods, density estimation and smoothing, image analysis, spatial statistics, visualization tools, interactive Web tools, and multipurpose statistics packages. Most are in C or Fortran. Most briefs offer a Technical Support Package , which explains the technology in greater detail and provides contact points for questions or licensing discussions. NASA Tech Briefs also contains feature articles on successful NASA spinoffs, profiles of NASA tech transfer resources, news briefs, and application stories.
Regular columns describe new patents, industry products, software, and literature.
The Journal of Astronomical Data accepts raw and reduced data from observations as well as from theoretical research, reduction software, complete descriptions of new instruments, PhD theses with extensive data tables, catalogues, graphs, computer code, and also lengthy articles, or regular articles accompanied by the data on which it is based. Contributions describe in short the astrophysical background and motive for the scientific work done, a complete description of the data-collecting process, an assessment of the accuracy of the data, next to the data themselves.
