Relativistic Coulomb excitations of odd-mass Po and Bi isotopes [1] were performed during the PreSPEC-AGATA campaign [2] at GSI to study the quadrupole collectivity in the direct vicinity of the heaviest stable doubly-magic nucleus 208Pb. The PreSPEC-AGATA campaign is the predecessor of the HISPEC (High-resolution In-flight Spectroscopy) experiment in the FAIR context. It was running 2012 and 2014 at GSI. Up to 23 AGATA crystals were used in this campaign, located behind the FRagment Separator. We will present the status of the ongoing data analysis and discuss the challenges of data analysis for this type of experiments.
