  "message": "Speed up the application of robust loss functions.\n\nSince we added special handling for the case for rho[2] \u003c 0,\nthe bulk of CorrectJacobian is pointless in the common case.\nSo add a simple one dimensional loop which rescales the Jacobian.\nThis speeds up this method immensely.\n\nThe robustification of a Jacobian gets speeded up by \u003e 50%.\n\nChange-Id: I97c4e897ccbb5521c053e1fb931c5d0d32f542c7\n",
