(a) Experimental phase diagram on cooling. (b) Experimental phase diagram on warming. Shown are the locations for the experimentally observed phase transitions. Black lines (solid and dotted) connecting the experimental data points are guides to the eye. Due to the experimental noise in our data, there is some uncertainty in locating the precise temperatures at which the superfluid fraction data deviated from the bulk contribution (Tc for the 3He in aerogel), the data changes slope (Tkink) and the locations at which the cooling and warming traces join (end of A-to-B and end of B-to-ESP transitions). These uncertainties are indicated with appropriate error bars.
