Representation of the parameters of proposed explosion mechanisms in the parameter space accessible to this study with Ṁ the mass transfer rate and M_WD, f the proposed total mass of the accreting WD at the point of detonation. If both values are provided by the source, each model is represented as a dot. If the source only provides a single value for M_WD, f, the model is represented as a blue line. If a range for M_WD, f is given, it is represented as pairs of colored lines with arrows indicating the position of the corresponding second line. Labels indicate source material as defined in Table 1.
