Guide to NuSTAR Cycle 5 Proposers
The start date for Cycle 5 has
been changed from June 1, 2019, to July 1,
2019; hence, Cycle 5 will last for a nominal
period of 11 months, see NRA clarification from February 19, 2019.
However, the observing time available for
Cycle 5 NuSTAR GO programs remains the same as
originally planned (~8.5 Ms). If there are projects requiring NuSTAR observations between
June 1 and June 30, 2019, such observations can be
NuSTAR Target of Opportunity (ToO) or
Directors Discretionary Time (DDT)
Observations. Due to the delay of the
Cycle 5 start time, approved Cycle 4
observations will extend into June, including
the opportunity to trigger Cycle 4 ToOs.
This NASA Research Announcement (NRA) solicits Guest Observer proposals
for NuSTAR. Approximately 8.5 Ms of time will be available
in the observing period
Proposals are due no later than March 29, 2019 4:30pm (EDT).
Note that the last day to request assistance for pointings with potential stray light to NuSTAR SOC is March 27th, 2019.
Call for Large Programs (>500 ks)A total of up to 2 Ms of NuSTAR Cycle 5 observing time will be made available for a new Large Program (LP) category. The minimum exposure time for LPs is 500 ks, and such proposals will have an additional page of text to describe the proposed program. Data from approved Cycle 5 LPs will have a one year exclusive use period after which the data will be placed in the public archive. A single-trigger ToO may be proposed as part of an LP (e.g., where a long observation is needed after the initial trigger). An approved LP with a ToO would have a six-month exclusive use period.
Joint Observing with NICERProposals for joint NuSTAR/NICER programs will be accepted up to a total of 250 ksec of NICER observing time. Joint proposals must provide a compelling justification of the need for both the NuSTAR and NICER data for achieving the primary science goals and receive a Category A or B rating to be considered for acceptance. NICER data sets obtained through approved joint NuSTAR/NICER proposals have the standard NuSTAR exclusive-use period and will be released publicly via the HEASARC data archive. Joint NuSTAR/NICER ToO proposals are only allowed for known sources (i.e., with known coordinates) in Cycle 5.
Additional details concerning Cycle 5 are given in the NuSTAR NRA. There will be a two-phase proposal process. Phase one is for observing proposals. Phase two is for budget proposals for successful phase one proposers who were awarded priority A or B targets. Only observing proposals will be accepted at this time.
Proposal submission is done via the HEASARC ARK/RPS on-line system. Hard-copy submission is not required. The following elements are required:
The following should not be submitted:
New NuSTAR PIs must first create an ARK account and/or join the NuSTAR RPS group. Having done so, the NuSTAR RPS form can be accessed via ARK/RPS.
We provide below some key details for NuSTAR Cycle 5. For further details, consult the ARK/RPS help file.
After completing all fields for a proposal in ARK/RPS, use the Verify button to confirm that all required entries exist and conform to the expected format. Forms that pass verification can then be submitted. ARK/RPS allows PIs to continue to modify submitted proposals until the deadline, so there is no penalty for submitting the proposal form early.
The LaTeX, PostScript, and PDF buttons of ARK/RPS can be used to generate formatted versions of the proposal forms. Although it is often useful for the PIs to keep formatted copies of the forms for the record, it is not a required part of the proposal submission process.
