- See Section 2.91.
- Response parameter is pseudo-velocity for 5% damping.
- For some periods (0.20s for vertical and 0.10 and 0.111s for horizontal) constrain c
_{2}to zero so that predicted amplitude would not decrease with increasing magnitude at zero distance. Note that does not affect uncertainty. - Note that long period filter cutoff may be too long for records from small shocks but if a shorter period was used then information on long period spectral ordinates would be lost. Note that insufficient data for well constrained results at M = 5 or M > 7.
- Find evidence for long period noise in d and in Degree of Magnitude Saturation (DMS = -(c
_{2}d∕b) * 100). - Examine median and normalized standard deviation (coefficient of variation) and find evidence for decreasing uncertainty with increasing magnitude.
