	# Build LCE map from s1 pattern map
	lcemap = deepcopy(self.s1_pattern_map)
	# AT: this scaling with mast is redundant to `make_patternmap`, but keep it in for now
	lcemap.data["map"] = np.sum(
	lcemap.data["map"][:][:][:], axis=3, keepdims=True, where=self.pmt_mask
	)
	lcemap.__init__(lcemap.data)
	self.s1_lce_correction_map = lcemap

changed in #350 is out of the box not compatible with the dummy maps we use for the public context. We need to update this.
