5/21/97
1. Error discovered in "corrected" multiplet Q values.  These
	values have been removed from the table of frequency
	and Q, and frequency-Q plots have been removed pending
	re-estimation of bias and uncertainty in Q.  We 
	apologize for any confusion or incovenience caused
	by the errant information.  At this time, we believe
	that the new corrections will be much smaller than
	those previously posted, and therefore our original,
	uncorrected Q estimates are still listed.

9/3/97
1. New degenerate frequency and Q table installed

9/16/97
1. New structure coefficient and error tables installed.  Most
	uncertainties have increased 10-20% relative to the
	previous catalogue.  
2. New structure coefficient plots installed.
3. Research description now includes a more detailed explain-
	ation of structure coefficient normalization.

11/3/97
1. Tables and plots of cross-coupling kernels replaced.  An error
   in the version of the subroutine used to generate the previous
   set of kernels has been corrected.  Changes are most significant
   for 1s3-3s1, 4s4-2t8, and 3s8-6s3.  Thanks to Chaincy Kuo of
   Berkeley who spotted symptoms of a problem in the 1s3-3s1 kernels.

11/12/97
1. Plots of cross-coupling structure coefficients changed to
	show corrected (see 11/3 note above) predictions from
	models S12_WM13 and SH.10c.17.
 
5/7/98
1. Updated references to Resovsky and Ritzwoller, 1998a,b.
2. Included links to abstracts (text files) of these papers
3. Removed link to non-existent degree 7 table
4. Added link to 2T branch page.
5. Added link resovsky@abdu.colorado.edu mailbox.
6. Added "3-D Mantle Models" section.
	* links to maps of CU degree 8 mantle shear velocity
	  model MM2_L12D8, which is the result of inversions
	  of our normal mode structure coefficient catalogue,
	  displayed together with maps of the spherical
	  harmonic degree 1-8 components of other recent
	  global models.
