The AFFINE TABLE depth offsets are determined using the tie/correlation/depth-shift features of the COMPOSITE tool under the PROCESS menu item. The depth offset values are determined when cores are depth-shifted to match core data from adjacent holes.
The AFFINE TABLE should be saved frequently as the compositing progresses. The file is written as simple ASCII text - these data can be downloaded and pasted directly into the Initial Reports volumes.
The Affine table format is as follows:
leg, sub_leg, site, hole, core, coretype, section, ODP depth, meters below seafloor (mbsf), depth offset (x.xx m), Y/N (Y=core has been correlated and depth-shifted), meters composite depth (x.xx mcd)
