- Square brackets show 2.5 and 97.5 percentiles of posterior probability density functions of the parameters
- 1Residual is defined as: \(\sqrt {\frac{{\mathop \sum \nolimits_{\varvec{i}}^{\varvec{N}} \left( {{\mathbf{Obs}}\left( \varvec{i} \right) - {\mathbf{Cal}}\left( \varvec{i} \right)} \right)^{2} }}{\varvec{N}}} ,\) where Obs is the observed displacement, Cal is calculated displacement, i is the pixel index, and N is the number of pixels used for the calculation
- 2Ratio of minor axis b to major axis a
- 3Dip angle δ is defined as δ = 0° if the ellipsoid is horizontal and δ = 90° if it is vertical
- 4Strike is defined as clockwise from the north
- 5ΔP/μ corresponds to ratio of pressure change (ΔP) to host rock rigidity (μ)
- 6Position of the southwest corner of the horizontal crack
