The cross sections are in the attached file. To generate them (assuming access to the grep-like tool ripgrep on RCAS) do:

rg "All included subprocesses" -g `ls  /star/embed/log/Pythia6*_4??_20184801/log/*.log` > Xsec_log_lines

And then can run the following script:
#!/opt/star/sl73_gcc485/bin/python

data = dict()
weighted = dict()

with open("Xsec_log_lines",'r') as f_in:
    for L in f_in:
        A = L.split('_')
        key = (int(A[1][2:]),int(A[2]))
        A = L.split()
        nevents = int(A[7])
        Xsection = float(A[10].replace("D","E"))

        if key in data:
            data[key].append((nevents,Xsection))
            weighted[key][0] += nevents
            weighted[key][1] += nevents*Xsection
        else:
            data[key] = [(nevents,Xsection),]
            weighted[key] = [nevents, nevents*Xsection]

# print to intermediate file:
with open("Xsec-nEvents",'w') as f_out:
    keys = data.keys()
    keys.sort()
    for K in keys:
        f_out.write('pthatrange: %-4i - %-i\n'%(K[0],K[1]))
        for val in data[K]:
            f_out.write("%i %g\n"%(val[0],val[1]))
# print weighted values:
with open('Xsec-pythia.txt','w') as f_out:
    keys = weighted.keys()
    keys.sort()
    f_out.write("(pthatrange)  nevents  weighted-Xsection\n")
    for K in keys:
        f_out.write(" %2i,%2i,      %8i,  %16g\n" %(K[0],K[1],weighted[K][0], weighted[K][1]/weighted[K][0]))
