   Many of the vertical sections were not mounted vertically in the instrument 
   for various technical reasons; therefore, the pattern of c-axes is actually 
   rotated from the vertical. The mount orientation of the samples is given in a 
   separate file titled 'sample orientation.doc.' This file contains a list of 
   all the samples specified by depth, followed by the tipping angle.

   To rotate the c-axes to 'vertical,' the following procedure must be used: 
   Convert the two Euler angles to unit vectors, and rotate the vectors by the 
   tipping angle about the z-axis.

   To rotate the c-axes to 'horizontal,' rotate the vectors about the x-axis by 
   90°.

   Most of the data were taken from the Siple Dome A core. The core hole for each 
   thin section is listed in the 'sample orientation.doc' file.

Group: Summary

   This data set contains measurements of the orientation and deformation of the 
   crystal c-axes (fabric) of ice core samples collected from the Siple Dome Ice 
   Core A, Antarctica (81°S, 148°W) between 22.764 m and 992.385 m in depth. The 
   instrument used for the measurements consists of a fiber-optic white light 
   source, one fixed black-and-white video camera, and four rotation stages. The 
   data are in ASCII tab-delimited text format and are available via FTP.
