BSHF
All samples move in time by a constant shift. The shift in seconds is either in the header for first break pick, or in a separate file. See Figure 87 for the example.
BSHF infile ipic ishf tshift picfil
infile: =input file name
ipic: 1=static shift data by picks pick file
0=static shift data by picks in headers
ishf: 0=add static shifts
1=subtract static shifts
tshift: =bulk static to add to picks
picfil: =file name with picks (for ipic=0)
Figure 87:
BGAZ: (A) Gained down-hole data, blue=direct wave, red=reverberating reflections (B) BSHF: Data flattened on down-going wave.
