*** READ RAW DATA ***

>>> Reading station data file
--> Processed CG-3m data file /home/gettings/projects/USGS_Nebraska/gravity/2003-09/alldata.txt with 1011 data records
>>> Reading station parameter file
->> Removing stations in skip list
--> Removed 1 of 1 stations in skip list (36 data records)
->> Checking for missing stations in parameter file
->> Removing parameter entries with no matching station data
->> Checking station repeat information for missing stations
--> station repeat information has 0 changes
--> Processed station parameter file /home/gettings/projects/USGS_Nebraska/gravity/2003-09/sep.par
>>> Reading tare data from file
!!! No tare data found in /home/gettings/projects/USGS_Nebraska/gravity/2003-09/09-23/grav.out.  Assuming no previous tare data.
--> done

*** VIEW UNCORRECTED DATA ***

>>> skipping view data

*** CORRECTIONS TO RAW DATA ***

>>> Pre-average corrections
->> Remove Longman Earth Tide Correction?
--> removing ETC applied by meter...done.
->> Remove Meter Drift Correction?
--> leaving drift correction applied by meter.
->> Atmospheric Pressure Correction?
--> no atmospheric corrections
->> Tamura Earth Tide Correction?
--> performing earth tide correction...done.
->> Tilt Correction?
--> not correcting meter tip/tilt corrections.
