Dynamic data links between tabs and status indicators

 
 
GSadjust links data across the data, drift, and network adjustment tabs. If station gravity values change (by unchecking samples in the Data Table on the Data tab), the respective gravity differences relative to that station on the Drift and Network Adjustment tabs are immediately updated. This facilitates an iterative workflow.
 
Although the gravity differences are updated, the network adjustment is not automatically repeated if station gravity values change. The user must repeat the "Adjust network" command on the Adjustment menu. If station gravity values have changed since the previous adjustment, a circular red indicator in the bottom right if the GSadjust window is shown. The indicator is cleared after performing the adjustment.
 
When changes are made to the current loop drift correction method (for example, changing the type from None to Continuous, or enabling the maximum time between repeats threshold, the respective delta-g's for that loop on the Network Adjustment tab are updated immediately and the adjustment results are invalidated. If the delta-g's for that loop aren't included on the Network Adjustment tab (for example, if the delta table has not yet been populated, or was populated with only a subset of loops, not including the current loop), changing the drift correction method won't affect the deltas on the Network Adjustment tab.
 
In addition to the station gravity values, the check status of each station in the left-hand tree view affects the data to be analyzed. When a station is unchecked, the delta-g's that include the station are immediately removed from the Drift and Network Adjustment tabs.
 
By disabling relative-gravity differences through unchecking one of the constituent stations, the influence of potentially bad station occupations can be rapidly assessed.
