NuSTAR Proposals and Tools
Prior to this, there was an opportunity to request NuSTAR time as part of a joint observing proposal with XMM-Newton, and there will be an opportunity to request NuSTAR time as part of a joint observing proposal with Chandra in Cycle 16 (proposal deadline is March 13, 2014).
Joint XMM-Newton and NuSTAR observation time was made available in the XMM-Newton Cycle 13 AO which was released on 27 August 2013, and 62 such proposals were in fact submitted. Such joint observations are planned to begin in May 2014. More details of this AO are available in Section 5.4.6 of the XMM-Newton Announcement of Opportunity, Policies and Procedures document and on the Caltech NuSTAR website.
An opportunity to propose for NuSTAR observing time as part of a joint Chandra/NuSTAR observing program is described in the Chandra Cycle 16 Call for Proposals. Up to 500 ksec of NuSTAR observing time will be made available through this AO. Proposals are due by March 13, 2014.
To help potential proposers, the standard HEASARC count rate and spectral simulations tools, WebPIMMs and WebSpec, are available. WebSpec was updated on September 5, 2013 to include the most recent NuSTAR responses and background files: note that there are two possible NuSTAR options, one for the 50% extraction region and the other for the 80% extraction region. WebPIMMS currently has an older version of the NuSTAR response but will shortly be updated to the most recent. The NuSTAR responses and background files can also be downloaded directly from here and used to simulate spectra in spectral analysis software such as XSPEC.
Other issues which proposers should take under consideration are:
