Joint Swift and NuSTAR Observations

NuSTAR and Swift have an arrangement which makes available joint observing time for both observatories. This resource allows observers to combine the powers of both observatories to bear on their scientific problems. This resource is extremely limited, so proposers should be sure to describe how their proposed observations exploit the unique capabilities of both observatories. While joint Swfit and NuSTAR proposals within the NuSTAR Guest Observer Program are now also possible, proposals for additional observation time can go through the Swift proposal process.
