Decimate, or reduce the sample rate of a set of traces stored in RSEIS format
DECIMATE.SEISN(TH, sel=1:length(TH$JSTR), dec=5 ,
type="LP", proto="BU" , fl=2, fh=10, RM=FALSE, zp=TRUE )
an RSEIS list.
RSEIS list
numeric, which traces to select
numeric, number of samples to skip
type of filter (see butfilt)
filter proto type
low pass frequency cut off
high pass frequency cut off
Remove mean value from trace, default=FALSE
zero phase filter, default=TRUE

Reduces the number of samples by skipping every "dec" sample. A filter is applied prior to decimation.
