Table 4
Comparison of the heavy PUI composition derived from CTOF data with the solar-wind composition (von Steiger et al. 2000; Shearer et al. 2014) and the modelled composition that one would expect from the production scenario proposed by Wimmer-Schweingruber & Bochsler (2003).

Notes. For the model, three different parameter sets were chosen (see text). The column x/x+/x++ denotes the fractions of neutral, x, single-charged, x+, and doubly-charged, x++, particles of a certain element at 1 AU in percent.
