AO-1 - CHEOPS Guest Observers Programme
The CHEOPS Time Allocation Committee (TAC) met on 2-3 July 2019. Details of proposals awarded time by the Director of Science, based on the recommendations of the TAC can be found at https://www.cosmos.esa.int/web/cheops-guest-observers-programme/ao-1-programmes.
The next opportunity to apply for observing time on CHEOPS will be when the Discretionary Time Programme opens, currently foreseen aroud the time of the start of routine operations/early 2020. Details will be posted on the CHEOPS Guest Observers webpages when available.

Prospective observers are requested to take note of the following points:
- All proposals must be submitted via the Phase I Proposal Handling Tool. Submission requires the use of a Cosmos Website ID together with membership of the CHEOPS Guest Observers Programme Group. Registration is required to download the software for the Scheduling Feasibility Checker, which is one of the tools needed to prepare proposals (see notes below) and also to download simulated CHEOPS data. Requests for both IDs and group membership need to be made by following the instructions at the following link: https://www.cosmos.esa.int/web/cheops-guest-observers-programme/register
We recommend that you get an ID/register early during the call.
- A minimum of 1 orbit per target, and a maximum of 100 orbits may be requested per proposal.
- It is important to appreciate that, due to the nature of the science that CHEOPS will address, the majority of CHEOPS observations will be time critical. These can be difficult to schedule, and in some cases it may not be possible even if a target is awarded observing time and is high priority.
- All tools and documentation, with the exception of ESA Phase I Proposal Handling Tool are provided by the CHEOPS Consortium, and are the same as those used by the Science Team to prepare the Guaranteed Time Observing Programme.
- Simultaneous scheduling of CHEOPS observations with other facilities will not be possible.
- CHEOPS is a small mission, with a correspondingly small team to support Guest Observers. Observers are advised to not to leave proposal preparation to the last weeks, as the response time incase of questions may be up to a few days.
- Notifications of any issues/updates to Call material will be published on the page at this link - prospectiver proposers are recommended to check this page regularly during the period of the call. ** UPDATED 29 April 2019 **
A number of tools and documents are available to help you with your proposal preparation.
Tools and supporting manuals:
- Phase I Proposal Handling Tool (proposal submission), presentation with instructions on use and multi-target upload file (csv);
- CHEOPS Exposure Time Calculator and manual;
- CHEOPS Scheduling Feasibility Checker installation instructions + user guidelines + details of FTP site);
*** Please note: May 2020: a new virtual image of the scheduling feasibility checker has been issued in preparation for the discretionary programme (cheopsfcvm06). More details on this can be found at the links above. Note that the installation instructions and guidelines are relevant to the NEW image. ***
