  We present a joint millimetric and X-ray analysis of hot gas properties in
the distant galaxy cluster SPT-CLJ0615-5746 ($z = 0.972$). Combining Chandra
observations with the South Pole Telescope (SPT) and Planck data, we perform
radial measurements of thermodynamical quantities up to a characteristic radius
of $1.2\, R_{500}$. We exploit the high angular resolution of Chandra and SPT
to map the innermost region of the cluster and the high sensitivity to the
larger angular scales of Planck to constrain the outskirts and improve the
estimation of the cosmic microwave background and the galactic thermal dust
emissions. Besides maximizing the accuracy of radial temperature measurements,
our joint analysis allows us to test the consistency between X-ray and
millimetric derivations of thermodynamic quantities via the introduction of a
normalization parameter ($\eta_T$) between X-ray and millimetric temperature
profiles. This approach reveals a substantial high value of the normalization
parameter, $\eta_T=1.46^{+0.15}_{-0.22}$, suggesting that the gas halo is
aspherical. Assuming hot gas hydrostatic equilibrium within complementary
angular sectors that intercept the major and minor elongation of the X-ray
image, we infer a halo mass profile that results from an effective compensation
of azimuthal variations of gas densities by variations of the $\eta_T$
parameter. Consistent with earlier integrated X-ray and millimetric
measurements, we infer a cluster mass of $M^{\text{HE}}_{500} =
10.67^{+0.62}_{-0.50}\,\, 10^{14}\,M_{\odot}$.
