### Setting Fit Options

Click Fit Options from the Bundle Alignment dialog box to open the Fit Options dialog box.

Typically, the default options (shown above) will be used. Select from the following options to determine how the Bundle Alignment solution is calculated:

- Normal Solution: Computes the orientation of each station and each "Bundle Alignment Feature" based on the current orientation of the stations and common "Bundle Alignment Features".

- Recalculate all: This recomputes the orientation of "Bundle Alignment Features" and stations disregarding current orientation of stations and common "Bundle Alignment Features".

- Keep oriented stations fixed: Previously oriented stations will remain unchanged and only the last station will be recomputed. The common "Bundle Alignment Features" will be recomputed.

- Keep points and oriented stations fixed: Both previously measured stations and the common "Bundle Alignment Features" will remain fixed.

- Balanced network: This is used to “balance” the system so that a single station is not constrained to be the origin.

- Blunder Analysis: This option makes the bundle program display the orientation results as computed by the approximation computations, before any adjustment is carried out. This is the best time to detect blunders, because blunders distort the parameters (coordinates and station parameters); the earlier blunders are detected, the better they can be identified.
