The dataset contains measurement of fixed point plateux induced in the Ag, Au, Cu, Fe-C, Co-C and Pd-C cells created by SMU during the project MultiFixRad (see the community to which this deposit belongs). The data file "smu_plateaux_txt" contains one plateau for each fixed point. It is a semicolon delimited text file with four columns: Fixed point, a string, and either Ag, Au, Cu, Fe-C, Co-C and Pd-C. For instance, each row labelled "Ag" is a datapoint recorded from the Ag cell. Count, an index into each row for each fixed point. The counter is reset every time a new fixed point is started. Duration since a start (a point during the initial rising flank just after the furnace temperature has been increased to above the melting temperature). Signal, as measured by a nanovoltmeter, in mV. The data file "Chino SMU spectral data" contains measured spectral response for radiation thermometer used. The file follows the same pattern as the other datafile, except that there are only two data columns: The wavelength, in nm The Chino response in mV. The third file is a short code snippet to load the data into Matlab.
