Regular Call for Semester 22B (Independently Funded Programs Queue)
|Semester start of observing
|2022-08-02 00:00 UT
|Semester end of observing
|2023-02-02 00:00 UT
Independently Funded Program requests are limited to a maximum of 200 hours; Once accepted through Hedwig a signed MOU will be required outlining the agreement between the observatory and PI's institute prior to obtaining data at the telescope.
- The ʻŪʻū (230 GHz) receiver of the Nāmakanui instrument
- The ʻĀweoweo (345 GHz) receiver of the Nāmakanui instrument, available on a “shared risk” basis (see below) for 345 GHz science in Semester 22B.
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. JCMT observations are conducted remotely on behalf of the proposers, in accordance with EAO flexible observing guidelines.
