+[Options]
+#> search the directory structure recursive for data files
+# recursive = True
+
+#> output weight tables: for APPLfast
+weights = True
+
+#> restrict merge to only certain columns: e.g. drop channel breakdown for performance
+# columns = ['tot_scale01', 'tot_scale02', 'tot_scale03', 'tot_scale04', 'tot_scale05', 'tot_scale06', 'tot_scale07']

+# The outlier rejection is controlled by two numbers:
+# - The threshold (something like a deviation from the mean in units of sigma;
+#   but computed in terms of the inter-quantile distances).
+#   Lowering this value will flag more points as outliers (default = 4).
+# - The highest fraction of points that are allowed to be removed.
+#   If step 1 flags too many points in a bin, adjust it dynamically to always stay below this fraction.
+#   This is a safety feature to avoid rejecting too many points (default = 0.05 = 5%).
+#
+# instead of ~4 sigma, start flagging at ~3 sigma
+#trim = (4, 0.05)
+#trim = (4, 0.08)
+#trim = (3, 0.05)
+#trim = (3, 0.08)
+trim = (3.5, 0.03)
+
+# By default do not use the option below to allow a better suppression of outliers.
+# However, if order independence is important like when cross checking two identical
+# NNLOJET inputs against each other, e.g. from a fixed- vs. flexible-scale grid comparison,
+# then do use the following option.
+#k-scan = (None, None, None)
+k-scan = (None, 3, 0.75)
