  An accreting system in two-temperature regime, admits multiple solutions for
the same set of constants of motion, producing widely different spectra.
Comparing observed spectrum with that derived from a randomly chosen accretion
solution, will give us a wrong estimation of the accretion parameters of the
system. The form of entropy measure obtained by us, have helped in removing the
degeneracy of the solutions, allowing us to understand the physics of the
system, shorn of arbitrary assumptions. In this work, we have shown how the
spectra and luminosities of an accreting system depends on the constants of
motion, producing solutions ranging from radiatively inefficient flows to
luminous flows. Increase in BH mass quantitatively changes the system, makes
the system more luminous and the spectral bandwidth also increases. Higher BH
mass system spans from radio to gamma-rays. However, increasing the accretion
rate around a BH of certain mass, has little influence in the frequency range
of the spectra.
