Chandra ACIS spectra of LTT 1445A (left) combined (top) and LTT 1445BC combined flare (middle), and quasi-quiescent (bottom). The corresponding right panels show the reconstructed continuous DEM distribution (approximated with a grid during the fit; see Fig. 4). The black curve shows the median of the posterior DEM predictions and the gray band contains 68% of the distribution. The colorful dotted lines are ten random posterior samples of possible DEM. The top right panel y-axis has a 100 times lower normalization than the lower-right panels. The bottom-right panel displays the DEM, with a narrow shape plummeting at 2 × 10⁷ K, while the middle right panel shows a broad distribution.
