Events detected in coincidence in the two detector layers are flagged as generated by Compton scattered photons and can be then processed and filtered using the Compton kinematic equations. The analysis of these data is, however, quite complex, mainly due to the presence of a great number of fake events generated by random coincidences between uncorrelated ISGRI and PICsIT events; if this component is not subtracted with great accuracy, false source detections can be produced. In this work, we present the performance (spectral and imaging) obtainable from the IBIS Compton data, by analyzing ground calibration acquisitions. We also analyze the IBIS Compton flight data relative to the Crab observation, to determine its scientific capabilities.STAMPAenConference paper10.1117/12.5549332-s2.0-10044296319https://api.elsevier.com/content/abstract/scopus_id/10044296319https://www.spiedigitallibrary.org/conference-proceedings-of-spie/5488/1/Performance-of-the-IBIS-Compton-mode/10.1117/12.554933.short2004SPIE.5488..738SFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
