The echo data contained in BI500 files are nominally "calibrated" Sv data created using a set of pre-calibration parameters contained in an .ekprm file that accompanies each BI500/EK500 data collection.
The user-input config parameters contain in the .ekprm file are often pre-calibration/nominal parameters. So, once careful new calibration is done, the calibration done using these pre-calibration/nominal parameters could be removed from the BI500 Sv data (these are more equivalent to the EK60/80 raw data), and new parameters can be applied to the "recovered-raw" data to get more accurate Sv values.
We need a function to do the above remove-reapply process to update the Sv data parsed from BI500 files to Sv calculated using more accurate parameters.
