To use it, you must first build a model file in which each object has two points: the first point placed on a point in the first data stack, the second point placed on the exactly corresponding point on the same section in the second data stack. This does not require very many objects - 10 should be plenty. Entries to the program are: Name of the model file containing the objects with corresponding points on an overlapping section. The Z value (typically the section #) for the points on the section in the first data stack. Only model objects whose first point has this Z value will be included 1 for a full report of deviations of points from perfect correspondence (see below) (After the program solves for a transformation): Name of the model file to be transformed 0 to transform model from fitting the first stack to fitting the second stack, or 1 to transform it from fitting the second stack to fitting the first stack. If the second point in each correspondence object has a different Z value from the first point (i.e. if the two data stacks do not have congruent Z coordinates), then the Z values of all points in the model being transformed will be adjusted by the difference in Z's of the cor- respondence points. When the program solves for the transformation between a pair of sec- tions, it applies the transformation to the points on the second sec- tion of the pair, and computes the displacement, or deviation, between each point and the corresponding point on the first section of the pair. It then reports the mean deviation for all of the points, the maximum deviation, and the object number of the point with maximum deviation. In addition, you may elect to have a complete report of the deviations of all points for particularly bad sections. If you choose this option, you control which sections are reported by specifying cri- terion values for the mean and maximum deviations; the full report will be made for any sections with mean or maximum deviations greater than the respective criteria.HISTORYWritten by David Mastronarde, 1/4/90BUGSEmail bug reports to mast at colorado dot edu.
