  Log Message:
  -----------
  guinier_search: maxrelsd parameter to exclude points with SD/I above a fraction

Off by default: such points carry little weight in the SD-weighted fit
(on a real extrapolated curve, dropping the first 9 noisy points moved Rg
by 0.1 A). Exposed on every interface for users who expect the leading
noisy points to be discarded as ATSAS does; the warning reports how many
excluded points fall below the end of the fitted range.
