Comments
Used 1500 m/sec for depth. See SVP's to calculate correctly, SBmrg.date-->SBmrg.datep.mb32 (basically just copies the file and adds the .mb32 extension, used mbprocess to do this) SBmrg.date-->SBfixavg.date SIO applies a ping-averaging algorithm to initially clean up the data. It is described as box averaging. (SIO programs to do this are sb2k_mbsysfix and sb2k_convert). SBfixavg.date-->SBfixavg.datep.mb32 (basically copies the file and adds the .mb32 extension, used mbprocess for this)
