Temperature and velocity distributions obtained in the framework of Model 1 with different time averaging of OMNI data as the inner boundary conditions at 1 AU. The left column presents calculations with one-minute OMNI data, the central column shows the same but with one-day-averaged OMNI data, and the right column the same but with 27d-averaged OMNI data. Blue curves show results of the model calculations. Red curves present Voyager data. Green curves present the stationary adiabatic solution.
