Left: HETG spectrum of π Aqr in black, which is the merged HEG and MEG first orders, excluding the high-hardness ratio observation (27325). In red is a model using three APEC components plus a Gaussian for the putative Fe K fluorescence. On the right, we compare the high-hardness ratio state spectrum (blue) to the rest (black and red).
