We encourage the use of CHEOPS public data for your science!
-> The official repository for CHEOPS data is at https://cheops.unige.ch/archive_browser/, where public data from all past and current CHEOPS Guest Observations (GO) and Guaranteed Time Observations (GTO) can be found. Alternatively, the Data Analysis Center for Exoplanets (dace.unige.ch) hosts all public GTO data, with enhanced and interactive visualization and analysis tools.
-> A lot of people are working daily to make CHEOPS and its observation programmes. We would be grateful if you could acknowledge this work. We kindly suggest getting in touch!
-> To enhance the visibility and traceability of CHEOPS data used in your articles, we recommend referencing the CHEOPS programme ID (CH_PRnnnnnn), ideally in a title footnote on the first page (e.g., via the LaTex \thanks{} command, ESO-style). For example: "Detection of the best exoplanet ever with CHEOPS\thanks{This study uses CHEOPS data observed as part of the Guest Observers (GO) programmes CH_PR00001 (PI LASTNAME1) and CH_PR00002 (PI LASTNAME2), and the Guaranteed Time Observervation (GTO) programmes CH_PR00003 and CH_PR00004.}"

-> Finally, please include the following acknowledgement:
"CHEOPS is an ESA mission in partnership with Switzerland with important contributions to the payload and the ground segment from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden, and the United Kingdom. The CHEOPS Consortium would like to gratefully acknowledge the support received by all the agencies, offices, universities, and industries involved. Their flexibility and willingness to explore new approaches were essential to the success of this mission. CHEOPS data analysed in this article will be made available in the CHEOPS mission archive (_https://cheops.unige.ch/archive_browser/)."_
If your paper makes use of CHEOPS Guest Observers (GO) and/or Guaranteed Time observations (GTO) data, best practices for describing the data are given in https://www.cosmos.esa.int/web/cheops-guest-observers-programme/publication-guidelines) and are repeated here:
If your paper describes the CHEOPS mission and instrument, please refer to: Benz et al. (2021), https://ui.adsabs.harvard.edu/link_gateway/2021ExA....51..109B/doi:10.1007/s10686-020-09679-4
If your paper describes the data analysis pipeline, please refer to: Hoyer et al. (2020), https://ui.adsabs.harvard.edu/link_gateway/2020A&A...635A..24H/doi:10.1051/0004-6361/201936325
If your paper discusses science performance and/or instrument performance and/or users calibration observations from the Monitoring and Characterisation programme, please refer to: Fortier et al. (2024), https://www.aanda.org/articles/aa/full_html/2024/07/aa48576-23/aa48576-23.html
An example description of the mission and pipeline might be (please do not copy&paste, but amend and edit as needed; update the DRP version if needed): "CHEOPS (Benz et al., 2021) observed the target on... The raw data of each visit were automatically processed by CHEOPS Data Reduction Pipeline (DRP, version XYZ, Hoyer et al. 2020). In short, the DRP performs an instrumental calibration (bias, gain, linearization, and flat-fielding correction), hot pixels correction and environmental correction (cosmic ray hits, background, and smearing correction) before extracting the photometric signal of the target in various apertures (Fortier et al., 2024). Here, we use light curves obtained with aperture XYZ. The File Keys of these data sets are listed in Table XYZ."
