Applying for AAT Telescope Time through ATAC
Important information for applicants
Time available for new proposals: Because of existing Large Programs and
other obligations, there are roughly 93 nights available for new
proposals in Semester 15A (12 dark, 19 grey, 62 bright). A call for
Large AAT Programs
/*not*/ be made in Semester 2015A. Proposals for Long Term AAT Programs
<https://www.aao.gov.au/science/observing/long-term-rules> are welcome
New proposal submission system
The AAO is moving to a new proposal submission system, known as Lens.
This system is a user account based system, which will allow for
improved security and better tracking of past and current proposals.
At present, we are still in the testing phase of Lens, but anticipate
that it will be available for general use from*Wednesday 20 August,
2014*. An email with more details will be sent via the ASA exploder.
Users who have applied for time as PI in the past four semesters (i.e.
starting from 2013A) have had accounts pre-configured. They will receive
an email with their login details in the days leading up to the launch
All other users are encouraged to register with the system at
/Note that users*cannot*be added to proposals if they are not registered
in Lens./Please make sure that all investigators on a proposal have
registered*well before the deadline!*
For any queries or comments, please emaillens at aao.gov.au
<mailto:lens at aao.gov.au>.
* UHRF will not be available for use in 15A.
* As of February 2014, AAOmega has a new blue CCD. This has increased
the throughput by an order of ~5% and, more importantly, is
cosmetically much cleaner with only 0.04% of the pixels flagged as
bad (compared to 0.8% for the old blue CCD).
* The AAO will replace the red CCD in AAOmega during Semester 14B.
This will provide a significant increase in throughput as well as
extend the throughput out to ~1 micron.
HERMES is now a general-user instrument. Questions about expected
instrument performance should be directed to the HERMES Project
Scientist, Gayandhi De Silva (gayandhi.desilva at aao.gov.au
<mailto:gayandhi.desilva at aao.gov.au>).
KOALA (Kilo-fibre Optical AAT Lenslet Array) has replaced SPIRAL as the
integral-field capability to AAOmega. KOALA has a 2x areal increase in
the field-of-view over SPIRAL (at the same spatial resolution), a
selectable spatial resolution of 0.7"or 1.25", an increase in throughput
at all wavelengths, particularly at the extreme blue, and simplified
field rotation.Information on KOALA
found in the instrumentation page and a new exposure time calculator is
available. Questions about expected performance should be directed to
the KOALA instrument scientist, Andy Green (andrew.green at aao.gov.au
<mailto:andrew.green at aao.gov.au>).
Since Semester 13A, remote observing from the AAO's North Ryde
headquarters has been available as an option for all AAT facility
instruments. We are developing a framework for offsite remote observing
at a later stage, in order to allow astronomers across Australia to
observe from their home institutions. Until that system is ready,
observers who wish to travel to Sydney to carry out remote observations
can continue to access the existing Travel and Accommodation
<https://www.aao.gov.au/science/observing/travel> support offered to AAT
If projects require fewer than 6 hours of observing time, they can be
performed in service time. Applications for service time are made
electronically direct to the AAO and reviewed every four months. See the
AAT Service Observing
<https://www.aao.gov.au/science/observing/apply/service> page for more
Applying for CTIO time-swap Time through ATAC
AAO-CTIO time-swap arrangement
The AAO and NOAO/CTIO have initiated a time-swap arrangement, to allow
our respective communities to maximise their scientific opportunities
through access to a broader range of facilities.
In Semester 15A there will be 15 nights available to the Australian
community to apply for CTIO time.
Generally a uniform distribution of lunations will be available to the
Australian community. This uniform distribution is particularly
important in B semesters (especially Sept-Nov) due to existing CTIO
commitments. Note, DECam has been demonstrated to produce useful imaging
in the reddest filters (izY) on all but the very brightest nights.
The DECam imager, the ISPI IR imager and the COSMOS spectrograph are
available for Australian proposals. COSMOS is available in an imaging
and longslit spectroscopy (slitwidth of 0.6" or 0.9") modes. The
multi-object spectroscopic capability of COSMOS is now available in a
shared-risk mode. All scheduled observations will be carried out in
classical mode with observers required to travel to the telescope.
Please review Current CTIO Instrumentation Status
CTIO Telescope Information
<http://www.ctio.noao.edu/noao/content/Instruments> for more information.
How to apply
Those who wish to apply for this time should do so using the Lens
proposal system, selecting "CTIO 4m" from the telescopes menu on the
first page of the proposal form.
The standard proposal page limits and recommendations regarding
technical justifications should be followed. The proposals will be
assessed by ATAC, and graded proposals provided to CTIO for scheduling.
How to Apply for AAT Time - the Basic Steps
Instrument status and policies
All ATAC applicants should check the latest Instrument Availability
<https://www.aao.gov.au/science/instruments/current/status> and recent
<https://www.aao.gov.au/science/observing/policies>. If you require
further clarification on any issue, then please contact the AAT
Technical Secretary (aatts at aao.gov.au <mailto:aatts at aao.gov.au>).
See Special Override Rules
proposals seeking time as an override on another program's time and the
Long Term Program
<http://www.aao.gov.au/science/observing/long-term-rules> page for those
seeking long term status. Proposals requiring at most 6 hours of
observing time should be submitted to the AAO's Service Observing
If the PI, and at least half the observing team are from European
countries, they may apply for AAT time through the OPTICON program
Full Technical Details, outlining how you derived your time estimates,
observing constraints, and any special requests should be included in
the scientific case (preferably under a separate section heading).
If your proposal seeks time on two instruments, outline carefully the
relative requirements of the different instrument set-ups, including the
split in observing time between the instruments.
If the observations are essential to the completion of a student's PhD
thesis, then a full explanation must be given in the science case. No
special consideration is given to proposals involving PhD students,
except when attempting to schedule proposals near the cut-off, when some
priority may be given.
All AAT applicants are required to *add on a 33% allowance for bad
weather* to the total time you estimate you will need to reach the
desired signal-to-noise, plus readout, slewing, and acquisition time.
All applicants should be aware that it is the policy of the AAO that any
backup project must use the same instrument as the main project.
A list of the principal targets (field centres for AAOmega+2dF programs)
should be prepared as a separate PDF document. The target list should
contain target name, RA (h m s), Dec (d m s), target brightness, and
priority. There is a 2-page limit for this target list PDF file. Other
document formats will not be accepted.
Proposal submission details
Prepare your main proposal offline, including an abstract, target list,
science case, and technical justification. The science case and
technical justification together should be, in PDF format, no more than
three pages total, with two pages for the science case and one page for
technical justification. The split into two pages science, plus one page
technical, is a change from previous semesters. Those three pages should
include all references and figures, use 11pt font (or larger), and have
at least 10mm margins. Colour figures are accepted. Other document
formats will not be accepted.
The limit for pre-approved Long-Term programs is five pages. Please
contact the ATAC Secretary, Helen Woods (helen.woods at aao.gov.au
<mailto:helen.woods at aao.gov.au>) well in advance of submitting this kind
Submitting your proposal
When your proposal details are ready, submit your application to ATAC
through Lens, the AAT's new proposal system. As noted above, this is a
user-account-based system and all investigators on a proposal*must*be
registered. Registration will open on Wednesday 20 August 2015 via
