We propose to complete the exposures for four targets that are part of ourMulti-Year Heritage Programe CHEX-MATE (2018-2021) to obtain homogeneous X-raycoverage. Aiming to study the ultimate products of structure formation in massand time through observations of a large unbiased signal-to-noise limitedsample of galaxy clusters detected by Planck via theirSunyaev-Zeli??i??i??dovich effect the CHEX-MATE observations have now beenfully executed. However a number of observations were severely flared and lackmore than 30% of the requested exposure time needed to meet our data qualityrequirement. Per the AO22 Policies and Procedures this Fulfil programme will..assist in the completion of the sample..and help homogenize the exposure ... [truncated! Please see actual data for full text]
