kappa stats:
  min = 0.038677
  max = 2.870492
  mean = 0.144925
  pixels with kappa > 0.5 = 2549
  pixels with kappa > 1.0 (strong-lensing regime) = 191

SL constraints used: 146 image rows, 55 source systems

Notes:
  This is a LITERATURE-INFORMED baseline using 2-NFW parametric model.
  Mass values from Bradac 2006 (M(<250 kpc) main = 2.8e14, bullet = 2.3e14).
  NOT a fit to SL constraints — that requires MCMC sampling (next iteration).
  This baseline provides reference kappa_observed for kappa_residual comparison.
