Imposed fit limits were as follows: aHS: 0.5°/°; bHS, σHSP, σBS, σHB, 50°; AOCR, 30°. SD values are not shown (n/a) when bootstrapped values formed a skewed distribution. aHS, Tilt-related increase in otolith noise; bHS, otolith noise in upright position; σHSP, width of head-tilt prior; σBS, noise in body-in-space sensors; σHB, noise in neck sensors; AOCR, uncompensated ocular counterroll.
