  PSZ2 G091.83+26.11 is a galaxy cluster with M500 = 7.43 x 10^14 Msun at z =
0.822 1. This object exhibits a complex morphology with a clear bimodality
observed in X-rays. However, it was detected and analysed in the Planck sample
as a single, spherical cluster following a universal profile 2. This model can
lead to miscalculations of thermodynamical quantities, like the pressure
profile. As future multiwavelength cluster experiments will detect more and
more objects at high redshifts, it is crucial to quantify this systematic
effect. In this work, we use high-resolution observations of the NIKA2
camera3,4,5,6 to integrate the morphological characteristics of the cluster in
our modelling. This is achieved by fitting a two-halo model to the SZ image and
then by reconstruction of the resulting projected pressure profile. We then
compare these results with the spherical assumption.
