      abstract     = {We report measurements of and meson photoproduction from
                      longitudinally spin-polarised protons by an energy tagged
                      (0.73-2.3 GeV) and linearly polarised photon beam. A close
                      to complete solid angle coverage for the reaction products
                      was provided by the CEBAF Large Acceptance Spectrometer at
                      Jefferson Laboratory. The double-polarisation observable is
                      extracted from Maximum Likelihood fits to the data, enabling
                      the first accurate determination for the reaction , while
                      also significantly extending the kinematic coverage for .
                      This large data set provides an important constraint on the
                      properties and spectrum of excited nucleon states decaying
                      to Nπ in the mass range from 1.4 to 2.2 GeV, as well as for
                      background (non-resonant) photoproduction processes. The
                      considerable improvement achieved in the description of the
                      observable within the SAID and Bonn-Gatchina approaches
                      after implementation of our data, illustrates that the
                      partial-wave analyses now significantly extend the knowledge
                      on Nπ photoproduction amplitudes at GeV. A partial-wave
                      analysis using the new high-precision data set has a large
                      impact on the extracted properties of high-spin nucleon
                      excited states.},
