Scatter plot of STIX counts (4 - 10 keV) versus GOES flux and histogram of STIX counts versus GOES flux as well as a linear fit to the data. STIX counts are background subtracted and multiplied by the squared distances between Solar Orbiter and the Sun. 1045 flares with Earth look-angles smaller than 90 degrees were selected.
The GOES flux of a solar flare is estimated using
flux=10^(p0+p1*x),
with x=log10(stix_peak_counts*r^2)
where p0, p1, p2 are the parameters from the curve fit, peak_counts is the STIX QL LC peak
counts and r is the distance between the Sun and solar orbiter in units of au.
