The AFFINE TABLE can be saved iteratively as the compositing progresses. As each core is depth-shifted to correlate with other depth-shifted cores, the AFFINE TABLE is internally updated with the depth offset value applied to each core and a binary (Y/N) switch value to indicate if the core has been depth-shifted (=Y).
When the AFFINE TABLE is opened, a verbose Affine Preview Window is also opened from the same directory as the AFFINE TABLE. This Affine Preview Window contains all information regarding the type of data which was read, what processing was done, and ODP ID and correlation information about the details of each composite and splice action on the current and equivalent (same site) previous dataset by the user.
A preexisting AFFINE TABLE can be read when core data are read-in initially to restore a previously-constructed composite depth scale. This is done by pressing the "READ AFFINE TABLE" button under OPEN DATA... menu item (under FILE). The previously-saved AFFINE TABLE (e.g. Sitexxxx.aff.out) is located and then selected by the user.
After core data have been read (and culled, smoothed, decimated as desired), the program applies the depth offset values contained in the AFFINE TABLE to the primary (ODP) core depth values. The core data are then plotted in the left-hand window in user-selected colors indicating whether the core has been shifted (composite depth default = light blue) or not (default = yellow).
See the AFFINE TABLE article for format information.
