Differential conductance data of point contacts measured at the edge of (Cr0.12Bi0.26Sb0.62)2Te3 / Nb heterostructures. As contained in arXiv:1809.04752. Three sets of data are included: Raw data of Contact 1 as shown in Fig. 2: "Datamtop.dat" contains raw data measured from negative fields towards positive fields. The data consists of pairs of columns containing bias voltage (V) and dI/dV (in units of 2e2/h). The labels mark the field values. In the publication the 175 mT data was subtracted as a background from the other field data. "Dataptom.dat" contains raw data measured from positive fields towards negative fields. The data consists of pairs of columns containing bias voltage (V) and dI/dV (in units of 2e2/h). The labels mark the field values.
