2020APR Release Notes

2020APR Observing Schedule Release Notes

Receivers: At the start of the semester the telescope will be fitted with the 20cm multi-beam receiver (MB20) and the Ultra Wideband Low (UWL) receiver. This will be the receiver fit out until the VLBI run in July when the mars and K band receivers will be installed in place of the UWL for a week. The UWL would then be re-installed following conclusion of the VLBI session. The primary control system for the UWL for this semester will be the DisH Astronomy GUi, DHAGU, named from the Wiradjuri phrase for ''where to?''- the main question any telescope-related software asks the observer. It is a web based graphical user interface to a control system based on the ASKAP Telescope Operating System (previously called TOS GUI).

Backends: The MEDUSA GPU cluster based system is the default system for use with the UWL. The DFB4 continues to be available, as does BPSR/HIPSR,and CASPSR.

Breakthrough Listen: The agreement between the Breakthrough Foundation and CSIRO to use the Parkes Telescope to Search for Extra-terrestrial Intelligence (SETI) continues. The Breakthrough Listen program will be allocated 25% of Parkes observing time for five years commencing in 2016OCT. For the 2020APR semester this equates to 750hrs, plus approximately 100hrs of make up time from previous semesters.

FAST: The agreement with the collaboration associated with the Five hundred metre Aperture Spherical Telescope (FAST) continues, identified as PX500 and PX501, and amounting to 205 hrs this semester.

Parkes Observing PORTAL: Parkes observers need to register for their upcoming observations, ideally at least two weeks in advance, using the PORTAL. Access to the PORTAL requires CSIRO unix or nexus account details: for users who do not have an account, account generation typically takes several working days.

Parkes Observing Support: Each Parkes project is required to designate a Project Expert from within the team who is the first point of contact for observing support for that team. Teams with no member suitable to be the Project Expert for that project should send an observer to the Science Operations Centre (SOC) in Marsfield in advance of the scheduled observing to be trained by ATNF Science staff. The Project Expert is expected to be capable of basic fault diagnosis/triage, and if not they will need to attend the SOC in person for training prior to future observations.

First-time observers will be required to undertake a telescope orientation session to introduce them to observing systems and monitoring tools. When first-time remote observers register their upcoming observing session(s) on the PORTAL they are sent links to on-line documentation and training material to help them prepare. It is a requirement that the on-line documentation is read before the training session. A list of the essential documents is given on the 'Help' and 'Links' tabs of the PORTAL.

Observers may choose to observe from the SOC at any time, and will be given a refresher or training session on request. Responsibility lies with the Principal Investigator (PI) to ensure the observers on their team are trained and competent observers. Observing from Parkes will be permitted for complex or non-standard observations, or in other circumstances where this is the more sensible option.

If anything remains unclear, please email ATNF-Parkes-Remobs[at]csiro.au or further clarification.

Radio Frequency Interference (RFI): Where possible notifications of expected RFI will be posted on the PORTAL Alerts. Other listings of known RFI are given on the Parkes observers pages.

Green Time: Directors Discretionary Time or 'Green Time' (so named after the colour scheme of the graphical format of the schedule, and not the system scientist) should be requested through the Portal. Instructions for doing this can be found in the "Book" tab in the Portal. Requests for green time can be made at any time during the semester, but the final allocation will not be made until ~1 week beforehand. Please also email Jimi Green (James.Green@csiro.au) with a summary of what you are requesting to observe.

Marsfield On-site Accommodation: The Marsfield site has a Lodge which is able to provide on-site accommodation for observers and DAs. Please use the new webform to book at least two weeks in advance to ensure a room is available.

Daylight Saving: Daylight saving in New South Wales will end at 3:00am (AEDT) on Sunday, 4th April 2020, when clocks will be put backward one hour. AEST is 10 hours ahead of UTC. Daylight saving in New South Wales will start again at 2:00am (AEST) on the first Sunday in October 2020.

Public Holidays: The Easter long weekend begins on Good Friday April 10, and continues through until Easter Monday April 13. The Anzac day Australia-wide public holiday falls on Saturday April 25. The Queen's birthday is a NSW holiday on Monday June 8.

Version history: Version 1 of the schedule was released on 2020 March 2nd. Version 2 of the schedule was released on 2020 March 13th, accounting for a change in CSIRO holiday dates, Parkes Show Day and additional project scheduling. Version 3 of the schedule was released on 2020 April 17th, with some minor project changes and addition of TOS testing and implementation time. Version 4/5 of the schedule was released on 2020 August 28th, for a shift of the P1066 project and associated changes for the period 14th to 22nd Sept.
