Inspecting the data

suwind < line.filter > s0508 key=sx min=05 max=08
suxwigb < s0508 title="s05 to s08" label1="Time (s)" label2="Trace numbers" &


Correlating the data

suxcor
suwind < s05 > s05.01 key=offset min=14 max=14
suwind < s0508 > s0508.01 key=offset min=14 max=14
suxcor < s0508.01 > s0508.corr sufile=s05.01
suxwigb < s0508.corr title="S05 - S08 correlations" label1="Time (s)" label2="Trace numbers" &


Shifting the shots

suwind < line.filter > s06 key=sx min=06 max=06
suwind < line.filter > s07 key=sx min=07 max=07
suxwigb < s06 title="s06 original" label1="Time (s)" label2="Trace numbers" &
suxwigb < s07 title="s07 original" label1="Time (s)" label2="Trace numbers" &
suresamp < s06 > s06.static nt=400 dt=0.0005 tmin=-0.0035
suresamp < s07 > s07.static nt=400 dt=0.0005 tmin=-0.002
suxwigb < s06.static title="s06 static shifted" label1="Time (s)" label2="Trace numbers" &
suxwigb < s07.static title="s07 static shifted" label1="Time (s)" label2="Trace numbers" &


Building the static corrected line

suwind < line.filter > line.static key=sx min=00 max=05
cat < s06.static >> line.static
cat < s07.static >> line.static
suwind < line.filter >> line.static key=sx min=08 max=24
suxwigb < line.filter title="Line before statics correction" label1="Time (s)" label2="Trace numbers" &
suxwigb < line.static title="Line after statics correction" label1="Time (s)" label2="Trace numbers" &
zap xwigb
rm s0508
rm s06*
