One of the key elements needed to perform cosmological exploitation a cluster survey is relation between observable and masses. Among these observables, integrated Compton parameter $Y$ measurable quantity in Sunyaev-Zeldovich (SZ) surveys, which tightly correlates with mass. The calibration $Y_{500}$ mass $M_{500}$ enclosed within radius $R_{500}$ one scientific goals NIKA2 SZ Large Program (L...
