Whether H72.97−69.39’s X-ray spectrum requires both thermal and non-thermal components

Determine whether the X-ray spectrum of H72.97−69.39 necessitates inclusion of both a thermal plasma component and a non-thermal (power-law) component, or whether a single-component model suffices given the current data quality.

Background

The paper fits H72.97−69.39’s X-ray spectrum with either a single thermal plasma or a single power-law model, both yielding statistically acceptable fits, but the limited net counts preclude robust multi-component modeling.

In comparing to RCW 38, where both thermal and non-thermal components are required, the authors explicitly state they cannot determine whether both components are needed for H72.97−69.39, leaving the spectral composition unresolved.
