## Automatic Picking Algorithm

### Description

Automatic Picking Algorithm

### Usage

    pickit(ay, deltat = 0.008, MED = 225, FRWD = 8, BKWD = 8,
     sbef = 1, saft = 6, thresh = 2, Tthresh2 = 7,
    stretch = 1000, flo = 0.1, fhi = 5, Kmin = 7,
    dthresh = 0.01, threshbot = 1.01)

### Arguments

`ay` | signal
`deltat` | sample rate
`MED` | use median smoothing?
`FRWD` | forward window, s
`BKWD` | backward window
`sbef` | seconds before
`saft` | seconds after
`thresh` | threshold 1
`Tthresh2` | threshold 2
`stretch` | stretch factor
`flo` | low frequency for BP filter
`fhi` | low frequency for BP filter
`Kmin` | min number of picks per window
`dthresh` | delta threshold
`threshbot` | threshold bottom limit

### Details

used internally. This code uses several methods for getting best pick.

### Value

list(RAT=A$rat, x=x, ay=ay, fy=fy, deltat=deltat, J=J$J , Z=Z, a1=a1, a2=a2, thresh=thresh, Tthresh2=Tthresh2, Kmin=Kmin)
