                    Caption: Figure A1.
NICER spectra for a sample marginal detection (1.2σ, top) and robust detection (13σ, bottom). We show spectra fit first with only the default SCORPEON components (representing the diffuse X-ray background and non-X-ray background), then with the addition of ionized oxygen lines from the SWCX, then with the addition of a tbabs×zbbody representing the source contribution.
