NPIPE CMB temperature analysis mask. This mask is derived by thresholding the standard-deviation map evaluated among the Commander CMB temperature maps resulting from three independent Planck processings (Planck 2015, Planck 2018, and NPIPE), multiplied by another mask, which is thresholded on an overall χ2 cut corresponding to the Commander NPIPE analysis.
