The 2023 2024 Open Call for Proposals is now CLOSED.The next call is expected to be issued in mid-March 2024 with deadline six weeks later OPEN. |
All proposals must be submitted using the MeerKAT Proposal Submission System (PSS). Prior to submitting a proposal, please ensure that you have done the following at the preparation stage:

Starting a new submission
Log into the MeerKAT Proposal Submission System homepage using your SARAO account credentials and click + New proposal and select the latest Call (“Batch”). First-time users should read the Getting a SARAO account page.
...
A PI can clone a proposal on which they were previously the PI, if the coversheets are largely unchanged.
...
Input the names, email addresses, affiliations and countries of all the members of the project. This includes the Principal Investigator*, all Co-investigators* and the Technical Lead*. As relevant also indicate whether the proposal is a core component of a PhD thesis.

Abstract (no more than 250 words).
Scientific categories (no more than three), and observation category. This helps allocate scientific reviewers to proposals.
Observation category. This helps during science as well as feasibility reviews.
Spectral line: Includes both 32K wideband as well as narrowband modes. While we understand that many observations will also make use of the continuum data for supporting or commensal science, select this if the spectral line observation forms an important part of the science case.
Continuum: Select this if your primary science case does not require high spectral resolution.
Image plane time domain: This refers to observations of slower transients that will be imaged using visibilities from the standard correlator modes.
Pulsars and fast transients: Select this category if you are going to be making use of User Supplied Equipment.
Proposal type category: Please refer to the Call document for definitions of the proposal types and time limits. Note that both Large and all categories can be Multi-year can be selected but Regular proposals preclude these categories .
Regular
Large: Large proposals must include details of pilot studies conducted prior to submitting this proposal.

or XLP and this indicates the number of years (2 - 4) that the proposal runs over.
Upload your science case as a pdf. Note that the pdf should be less than 10 MB and not exceed 3 pages for Regular proposals. Large proposals may submit up to 4 pages and XLP are limited to 8 pages.
Targets/Fields
Attach/input (J2000) coordinates of your proposed targets, if they are known, as well as the requested integration time per target in seconds, excluding calibrators and calibration overheads. In the case of Target of Opportunity observations, subject to triggering criteria, you may tick the box to submit the proposal without specific targets. The triggering criteria must be clearly defined under the ‘Observation’ section. Also if, for instance, your project aims to cover a wide contiguous area of sky, you may choose to note those details in the ‘Additional Information’ box on the last page rather than submitting many individual targets. The total time for targets must be less than or equal to the total time on the Observation Details page, which includes calibrators and calibration overheads.
Large target lists may be uploaded as csv files.
Only targets of the format: NAME, RA, DEC, TIME will be imported.
sample: J0408-6545, 04:08:20.123, -65:45:09.61, 180
Both the RA and DEC coordinates can have arbitrary precision. However, RA will be truncated to 3 decimals, whereas DEC will be limited to 2 decimals.
Time, in seconds, is limited between 1 and 1440000.
A window will show a table of discarded targets, if any, stating the invalid fields under the REASON column.
Note that duplicate targets (same RA and DEC) will also be discarded.

Observation details
Observation Page
Multiple simultaneous sub-array indicator added
The observation details form has been significantly expanded from 20222023. Please read the Call document for conditions pertaining to time requests, including multi-year proposals.
Spectral zoom modes are only available for L-band at this point.
Limits for time are as follows:
Regular: 0.1 - 100 hrs overall
Large: 100.1 - 300 hrs overall
XLP: 300.1 - 2200 hrs overall (but you can only request a max of 500 hrs for this year)
S-band
limit to 100 hrs overall
Multiple bands can be requested. The time request for each band must be entered into this form.
...
Multiple simultaneous sub-array indicator has been added if multiple arrays/bands are observed at the same time.
Choose between imaging or beamformed observations. Note beamformed observations can also include imaging. Selecting beamformed observations triggers a new dropdown selection box for User Supplied Equipment.
Choose the observing band(s), integration period, correlator channelisation, and centre frequency in the case of narrowband modes.
Indicate the amount of observing time (including overheads) that you are requesting. Note that for standard calibration schemes an overhead of 25% can be assumed. If different overhead fraction/time is expected (different calibration scheme, many short slews, etc), this must be justified in the Science Case and the OPT must be used to simulate the observations. Short observations (< 2 hours) tend to have much higher overheads due to the larger proportion of time spent on the bandpass calibrator. Please refer to our page on average overheads for further details.
In certain cases, night time observations may be necessary, e.g. to avoid solar interference or because simultaneous optical observations are planned. Note that night observations tend to be more oversubscribed and your preference needs to be justified in the Science Case.
For multi year proposals there will be an additional field in band selection, defining many hours in this 12 months cycle and how many in the proposal altogether .
For target of opportunity (ToO) observations, the triggering criteria must be clearly specified.
...
Multiple simultaneous sub-array proposals should be confirmed with the observatory before submitting.
Data management
MeerKAT datasets, particularly for spectral line modes, can become extremely large. Use the data volume calculator to estimate the size of the measurement set to be downloaded. Remember that you will need several times this in disk space to process the data.
Specify where you are planning to reduce the data. The compute requirements may be considerable.
Many of our users have experienced challenges in downloading data. Please indicate how you plan to transfer the data to the processing facility. Users who may need to download many terabytes of data and who have a slow internet connection may wish to make prior arrangements with SARAO to ship tapes (if they have the appropriate tape drives).
If the proposal type is

You may wish to consider using the SDP pipeline and images for some purposes, particularly if rapid feedback is necessary.
Upload a one-page pdf detailing the data management plan including relevant experience of the team (see the Call document for details).
