Spatially resolved conversion factor (W_[CII]) as a function of different physical properties within 30 pc size pixels in the ISM of the three galaxies shown in Fig. 2. We show the mass-weighted KDE of pixels in the W_[CII] − Z plane (top row), W_[CII] − n plane (middle row), and W_[CII] − ℳ plane (bottom row) for Lantana (z = 7.03, left), Adenia (z = 6.28, center), and Malva (z = 4.13, right). In each panel, we also show the [CII]-weighted KDEs with gray contours. The global ([CII]-weighted) value of α_[CII] for each galaxy is reported with a dashed (solid) line.
