Urgent Call for Semester 21A
This is a call for urgent proposals. For regular calls for proposals, please see the facility home page.
|Semester start of observing||2021-02-02 00:00 UT|
|Semester end of observing||2021-08-02 00:00 UT|
|Call for proposals closing date||2021-08-01 00:00 UT|
The East Asian Observatory invites requests for urgent observing at any time with Principal Investigators (PIs) from its partner regions (China, Japan, South Korea, Taiwan), from Indonesia, Malaysia, Thailand or Vietnam, or from eligible PIs in the UK/Ireland. All prospective PIs should review the JCMT eligibility requirements page prior to the preparation and submission of a proposal.
Urgent Requests should clearly describe the following:
- The urgency for the observations, and why a response to the regular, semi-annual call for proposals is/was inappropriate.
- The time span over which observations may be made or the specific times at which they must be made.
- The timescale for analysis of resulting data and for publication thereof, which ought to be proportionately urgent.
The above information should appear in the Scientific Justification section of the proposal, as itemized above.
If approved, proposals will be graded with respect to the approved projects in the current semester and executed via the JCMT’s flexible observing scheme.
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.
- Spectroscopically, this involves observations of one of the JCMT spectral line standards at one of about ten different line frequencies. If the target observing frequency is one of these, then the proposers are in luck. In any case, the calibration allows the proposers to assess the performance of the instrument. Such an observation will be performed at least once per program unless a previous calibration is still appropriate, and more often if circumstances change or if more than a couple of hours pass.
- For continuum work, calibrators will be observed at both operational wavelengths of SCUBA-2 (450µm, 850µm) at appropriate times and airmasses to meet the general needs of the science program.
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.
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.
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.
For any remaining further questions, please use the “Contact us” link at the bottom of any page of the proposal submission system.
The following queues have open calls for this semester. Please select a queue to start a new proposal.
|Call for proposals opens||2021-02-01 00:00 UT|
|Call for proposals closes||2021-08-01 00:00 UT|
This is the combined queue used for all JCMT PI proposals other than University of Hawaii projects.
This queue is available for Principal Investigators (PIs) with one of the following affiliations:
- Canada (listed institution)
- Canada (national — for institutions other than those listed)
- EAO Staff (Hilo, Hawaii)
- South Korea
- UK & Ireland (listed institution)
Please see the eligibility requirements page for more complete information.
Other (non-PI) members of the proposal can use the special affiliation “Other” if none of the above affiliations apply.
