With the release of Oasis montaj 9.9, we made a change to the gravity processing workflow. In previous versions of Oasis montaj (9.8 and earlier), the Latitude Correction used to correct for Normal Gravity was included automatically when calculating the Free Air Anomaly and Bouguer Anomaly.
In version 9.9, the Latitude Correction is a separate correction that must be run independently.
In Version 9.9 and later you will need to run this Latitude Correction before calculating Free Air, Bouguer and Complete Bouguer.
Why did we make this change?
We found that many end-users wanted to see the Latitude Correction separated from the standard corrections for greater visibility into the Latitude Correction. We now provide the LatCor channel with these correction values (Normal Gravity).
