The polarization of emissions from the Crab, as measured during the flight in 2016 is reported for the energy range (~20-160 keV). The Crab is a complex system consisting of a central pulsar, a diffuse pulsar wind nebula, as well as structures in the inner nebula including a jet and torus. Source and background observations are interspersed allowing for a rigorous background subtraction eliminating systematic effects. The polarization vector is found to be aligned with the spin axis of the pulsar for a polarization fraction, PF = (20.9 <span class="mo">±</span> 5.0)%. Contrary to measurements at higher energies, no significant temporal evolution of phase-integrated polarisation parameters is observed. Through phase selections the off-pulse (OP) and pulsar (P1, P2) can be studied separately. The polarization properties of nebula dominated OP are compatible with the phase-integrated results. The polarization parameters for the pulsar itself (P2) are measured and are consistent with observations at optical wavelengths. Additionally, the instrument design and analysis methodology is detailed.</div><p style="margin-top: 0px; margin-bottom: 0px; color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class=""></p><div style="margin-top: 0px; margin-bottom: 0px; color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class=""><br class=""></div><div style="margin-top: 0px; margin-bottom: 0px; color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class=""><br class=""></div><div style="margin-top: 0px; margin-bottom: 0px; color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class=""><br class=""></div><div style="margin-top: 0px; margin-bottom: 0px; color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class="">cheers</div><div style="margin-top: 0px; margin-bottom: 0px; color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class=""><br class=""></div><div style="margin-top: 0px; margin-bottom: 0px; color: rgb(33, 33, 33); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;" class="">/Francesco</div><div apple-content-edited="true" class="">
