Criteria for picking of clear HVSR peaks (adapted from Wang 2020). Values of Wang (2020) are shown in bold when updated from the SESAME values
| Criteria | SESAME | Wang (2020) |
|---|---|---|
| Clear 1: f ∈ [0.25f#HV,f#HV] | AHVave(f) < 0.5A#HV | AHVave(f) < 0.6A#HV |
| Clear 2: f ∈ [f#HV, 4f#HV] | AHVave(f) < 0.5A#HV | AHVave(f) < 0.6A#HV |
| Clear 3 | A#HV ≥ 2 | A#HV ≥ 1.6 |
| Clear 4: peak of f#HV [AHVave(f)-σA(f)] | within [f#HV /1.05, 1.05f#HV] | within [f#HV /1.15, 1.15f#HV] |
| Clear 4: peak of f#HV [AHVave(f) + σA(f)] | within [f#HV /1.05, 1.05f#HV] | within [f#HV /1.12, 1.12f#HV] |
| Clear 5: f#HV < 0.2 Hz | σf < 0.25f#HV | Recommends removal of Clear 5 criteria (barely satisfied) |
| Clear 5: f#HV ∈ [0.2, 0.5] Hz | σf < 0.20f#HV | |
| Clear 5: f#HV ∈ [0.5, 1.0] Hz | σf < 0.15f#HV | |
| Clear 5: f#HV ∈ [1.0, 2.0] Hz | σf < 0.10f#HV | |
| Clear 5: f#HV > 2.0 Hz | σf < 0.05f#HV | |
| Clear 6: f#HV < 0.2 Hz | σA < 3 | No change from SESAME |
| Clear 6: f#HV ∈ [0.2, 0.5] Hz | σA < 2.5 | No change from SESAME |
| Clear 6: f#HV ∈ [0.5, 1.0] Hz | σA < 2 | No change from SESAME |
| Clear 6: f#HV ∈ [1.0, 2.0] Hz | σA < 1.78 | No change from SESAME |
| Clear 6: f#HV > 2.0 Hz | σA < 1.58 | No change from SESAME |
Rows labeled Clear # represent the #-th condition for a clear peak. f#HV is the variable of interest (there could be multiple f#HV values in a single curve), A#HV is the amplitude at f#HV; AHVave(f) is the amplitude of HVSR mean curve at frequency f; σ(f) is standard deviation of f#HV, and σA(f) is standard deviation of AHVave(f)
