Content of Proposal

Proposal authors are expected to provide separately both a Scientific and a Technical Justification for their proposed observations. These justifications should be substantiated by results from the JCMT integration time calculators to show that the proposed observations will reach the necessary noise limits for the proposed science goals. The calculators are integrated into the proposal submission system, and should be used to save the calculation(s) for their inclusion in the proposal.


Overheads for pointing, focusing, and calibrations should not be added to the time request. These activities will be accounted for separately. Calibration observations (e.g. focus, pointing, flux calibrators) and other unavoidable overheads (e.g. receiver tuning) are not charged to science projects and instead are charged to an Observatory accounting code. There is therefore no need for applicants to provide calibration overhead estimates in their proposals. The Observatory will perform regular and appropriate calibration observations to ensure that all science data obtained are sensibly calibrated.

If a proposal demands more unusual or more frequent calibrations then this needs to be clearly stated in the proposal and the time for these calibrations requested explicitly. For queries about what the default calibrations might be, or what extra overheads are generated by a project’s calibration requirements, please consult JCMT staff.

Previous Proposals

The proposers should provide information on any previous successful (or otherwise) JCMT proposals, including any papers published as a result or the status of the project. The success of previous projects can be taken into account when awarding time, so it is in the proposers’ interests to provide full information on this. A section is included within the proposal submission system for this information.

Data Available from the Archive and Large Programs

All proposers are expected to check that there are no preexisting public data that meet the proposal’s science needs, or conflicting large programs, before submitting a proposal. A clash tool is available to aid in this, which can be used to search for potential “clashes” between the proposed objects and available data sets. It also provides a link to an archive search for each target position.

It is the proposers’ responsibility to ensure that sufficient explanation is included as to why any matching data does not meet the project’s needs — e.g. because it does not reach sufficient depth, or because is not at the right frequency, or because the observations were not of sufficient quality.

The ‘Outreach’ version of the proposed science

In the ‘Public Summary’ section, proposers should provide a paragraph describing the goals of the proposal in a way that is understandable to a general (non-scientific) audience. This may be used in JCMT outreach efforts.

Flexible Scheduling

The overall philosophy of observing at JCMT is to match observing programs to the weather — see the Flexible Observing Guidelines page for more information. JCMT observations are conducted remotely on behalf of the proposers, in accordance with EAO flexible observing guidelines.

Shared Risk Observing (ʻĀweoweo)

The Observatory offers this opportunity with the strong caveat that this observing mode is still under development and/or commissioning. Scientific results cannot be guaranteed for sensitivity, calibration and/or reliability without further work between the project observers and Observatory staff. The Observatory will make best efforts to assist scientists with the observing request, data acquisition and reduction, and result analysis. Time will not be returned to the project should the needed sensitivity or other parameters not be met.

Further Questions

For any remaining further questions, please use the “Contact us” link at the bottom of any page of the proposal submission system.
