A High Spectral Resolution Study of the Soft X-ray Background with the
  X-ray Quantum Calorimeter
  We present here a combined analysis of four high spectral resolution
observations of the Diffuse X-ray Background (DXRB), made using the University
of Wisconsin-Madison/Goddard Space Flight Center X-ray Quantum Calorimeter
(XQC) sounding rocket payload. The observed spectra support the existence of a
$\sim0.1~$keV Local Hot Bubble and a $\sim0.2~$keV Hot Halo, with discrepancies
between repeated observations compatible with expected contributions of
time-variable emission from Solar Wind Charge Exchange (SWCX). An additional
component of $\sim0.9~$keV emission observed only at low galactic latitudes can
be consistently explained by unresolved dM stars.
