Calculate PDF

process_one_channel(S::SeisData; response::AbstractArray=Array{Complex{Float64}}(undef, 0), smooth_width_factor::Float64=1.25, min_db::Int64=-200, max_db::Int64=-50, divide_by_period::Bool=false)

Process the first channel of trace and return its PDF and center periods.

Arguments

• S::SeisData: A trace.

Optional

• response::AbstractArray: instrument response presented in frequency domain.
• smooth_width_factor::Float64: smoothing width factor to control the range of calculating PSD.
• min_db::Int64: minimum threshold of PDF binning. Measured in dB.
• max_db::Int64: maximum threshold of PDF binning. Measured in dB.
• divide_by_period: divide each PSD bin in period rather than count. Such a non-sense.
