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.


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.
