# Remove logarithms of amplitude factors produced by 'wfcalib'

# Input records are selected by headers 'vintage' and 'kfilt'
# These records are supposed to be produced by 'wfcalib', whuich outputs
# into the third trace components logaruithms of amplitude scalars.
# In this example, these amplitude scalars are removed within the time interval
# between 'top' and 'bottom':

*call	gain	remove		# will REMOVE the scaling factors applied during calibration 
scmode	log			# input parameters LEVEL below are interpreted as logarithms of gain scalars
