Angle change data used in 1906 earthquake slip estimation. Each observed angle is defined by three triangulation stations, numbered as in Table A1, with the second number listed corresponding to the station from which the angle was turned, clockwise from the first station number to the third. Calculated angle changes and data importance are for the preferred slip model listed in Table 1 and illustrated in Figure 4.
