HOYS Publication Guidelines
All publications using any HOYS data should reference the project description paper (Froebrich et al. 2018, MNRAS, 478, 5091) and the data calibration paper (Evitts et al. 2020, MNRAS, 493, 184). If not all contributors of data are included in the author list, then the following should be added to the acknowledgements of every publication: “We would like to thank all contributors of observational data for their efforts towards the success of the HOYS project.”
We aim to disseminate the results of the science exploitation of the HOYS data with two kinds of publications. These are: i) larger, survey description type publications and ii) smaller, more specific publications.
We plan to write type i) publications about every one to two years. On these publications every participant who contributed data should be added as a co-author (if s/he wishes so), as well as everyone involved in the data analysis.
All other, type ii) publications using any HOYS data should include everyone as a co-author who made a significant contribution to the scientific analysis of the data and the preparation of the publication. Furthermore, any contributor who made a significant contribution to the dataset analysed in the publication should be added as co-author. In other words, anyone whose data cannot be removed without significantly degrading the quality of the analysis should be made a co-author.
