This dialog provides options for performing the network adjustment. Options 1-4 are used to calculate the value shown in the "SD for adj." column of the Delta Table, which is the standard deviation used in the network adjustment.
Standard deviation multiplier, pre-minimum
When checked, multiplies the delta-g standard deviation (determined from the data and/or drift-correction method) by the specified value prior to enforcing the minimum standard deviation (if checked). May be used in conjunction with "Add to std. dev." (multiplier is applied first).
When checked, multiplies the delta-g standard deviation (determined from the data and/or drift-correction method) by the specified value after enforcing the minimum standard deviation (if checked). May be used in conjunction with "Add to std. dev." (multiplier is applied first).
When checked, adds the specified value to the delta-g standard deviation (determined from the data and/or drift-correction method) prior to enforcing the minimum standard deviation. May be used in conjunction with "Add to std. dev." (multiplier is applied first).
When checked, the delta-g standard deviation used in the adjustment is the greater of the specified value, or the standard deviation determined from the data and/or drift-correction method.
When checked, a relative-meter calibration coefficient (scale factor) is calculated during the network adjustment. The calibration coefficient is a multiplier applied to all relative-gravity observations. It is calculated from the datum observations in a network, and 2 or more datum observations are required. If more than one relative-gravity meter is used on a survey, the calibration coefficient must be calculated or specified for all meters (if not specified, it is set to 1.0).
When checked, the specified relative-meter calibration coefficient is applied during the network adjustment. The calibration coefficient is a multiplier applied to all relative-gravity observations. A coefficient for each meter must be provided in the calibration coefficient table.
If the Specify calibration coefficient checkbox is checked, each delta-g is multiplied by the gravity-meter specific coefficient in the calibration coefficient table.
Applies the network-adjustment options to the survey curently selected in the data tree view at the left side of the window (The current survey is highlighted in bold).
