Rapid Turnaround Call for Semester 20X

This is a call for rapid turnaround proposals. For regular calls for proposals, please see the facility home page.

Semester Information

Semester start of observing 2020-03-16 00:00 UT
Semester end of observing 2020-08-02 00:00 UT

The East Asian Observatory invites JCMT observing proposals with Principal Investigators (PIs) affiliated with a South Korean institution only for a special supplementary Call for Proposals. All prospective PIs should review the JCMT eligibility requirements page prior to the preparation and submission of a proposal. The length of the proprietary period for all data taken for successful proposals shall be the usual 1 year.

Proposals for this special “Rapid Turnaround”-style Call are limited in accordance with the following constraints:

The proposal submission deadline for this special 19B Supplementary Call for Proposals is February 28th, 2020.

All proposals submitted for this Call shall be peer-reviewed by the proposal creator (or designated co-author) of other proposals also submitted for this Call.

The proposal Peer Review deadline is March 7th, 2020.

By submitting a proposal, all proposing teams are committing themselves to providing ratings and brief written assessments of several other proposals submitted for this Call by this deadline.

Any proposing team that fails to provide a full set of reviews for their assigned proposals by the above review deadline shall have their own proposal removed from the review process. All such proposals shall be regarded as abandoned by the Observatory.

Important Notes

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. Data may then be acquired for a project at any time, even without the applicants being in attendance at the telescope. A summary was also given at the January 2015 Workshops.

Observer status

The “Members” section of the proposal form should be used to express the proposers’ willingness and ability to travel and observe.

The JCMT will primarily be run in “Remote Operations” mode for the entirety of the semester. For observing teams that have submitted projects of unusual technical complexity or projects that make use of unusual observing/calibration modes, however, the Observatory may invite visiting observers to come to the Hilo and/or summit facilities in order to directly participate in the execution of JCMT observations.

In addition, programs with PIs/Co-Is new to the JCMT are strongly encouraged to visit the Observatory to learn more about the telescope, data acquisition and data reduction and provide seminars.
