  The NIKA2 camera operating at the IRAM 30 m telescope excels in high-angular
resolution mapping of the thermal Sunyaev-Zeldovich effect towards galaxy
clusters at intermediate and high-redshift. As part of the NIKA2 guaranteed
time, the SZ Large Program (LPSZ) aims at tSZ-mapping a representative sample
of SZ-selected galaxy clusters in the catalogues of the Planck satellite and of
the Atacama Cosmology Telescope, and also observed in X-ray with XMM Newton or
Chandra. Having completed observations in January 2023, we present tSZ maps of
38 clusters spanning the targeted mass ($3 < M_{500}/10^{14} M_{\odot} < 10$)
and redshift ($0.5 < z < 0.9$) ranges. The first in depth studies of individual
clusters highlight the potential of combining tSZ and X-ray observations at
similar angular resolution for accurate mass measurements. These were
milestones for the development of a standard data analysis pipeline to go from
NIKA2 raw data to the thermodynamic properties of galaxy clusters for the
upcoming LPSZ data release. Final products will include unprecedented
measurements of the mean pressure profile and mass observable scaling relation
using a distinctive SZ-selected sample, which will be key for ultimately
improving the accuracy of cluster based cosmology.
