CTIO Blanco 4-m Telescope Target-of-Opportunity Observing Program Policies.
For the attention of: CTIO staff, Blanco 4-m telescope observers,
CTIO Blanco 4-m telescope ToO program principal investigators.
Updated on: 6 Oct 2010
CTIO follows the NOAO
Target of Opportunity observing program policy with the addenda given
below for the
V. M. Blanco 4-m telescope.
We thank observers for their forbearance and co-operation with these policies.
- Call-up Procedure
The regular observer should hear about a ToO as soon as possible,
preferably no later than the afternoon of the observing night.
That allows the observer to email back and forth with the PI
of the ToO program.
To initiate the process of triggering an observation for their
Target of Opportunity Program, the approved program PI or specified
(1) Contact the observer(s) using the telescope --
the Blanco console phone number is +56-51-205-400
(2) Email mosaicToO@ctio.noao.edu each time a request
is made for observations
- Data taking
(1) The current observer will be asked to take the ToO data following the
detailed recipe furnished by the calling team. The ToO PI or deputy
must forward the instruction given to the observer to
(2) Any images taken specifically for
a ToO program should be identified with the NOAO proposal number
(click here for a
list of current approved ToO projects) to make it easier to
identify in the NOAO
data archive. Use obspars or equivalent to put the information
in the headers and be sure to restore the Proposal ID for the scheduled
observer after the ToO observations have been completed.
(3)The observer must include in their night report when a ToO observation
is requested, and the amount of time the observer dedicates to the ToO.
- Data Distribution
The current protocol for ToO data distribution can be found
at Target of Opportunity data files.
The following table lists those persons authorized to initiate a ToO
ToO interrupts should be issued only for observations that are time critical. Non-time-critical followup observations should be pursued through other means.
ToO PIs may not specify observing conditions under which the ToO observations are made; either the ToO observations are triggered or they are not.
If a called ToO is clouded out then the time is charged, just as if the
observations were made. The same is true of instrument/telescope failures.
ToO observations are authorized only for NOAO assigned telescope time. Observing runs assigned by the Chilean TAC may only be interrupted upon the consent of the scheduled observer.
