Spatial aliasing and scale invariance, another chapter of Jon Claerbout‘s book Image Estimation by Example is added to the collection of reproducible papers (with code fragments translated from Fortran-90/Ratfor/Loptran to C).

Multidimensional autoregression, another chapter of Jon Claerbout‘s book Image Estimation by Example is added to the collection of reproducible papers (with code fragments translated from Fortran-90/Ratfor/Loptran to C).

Empty bins and inverse interpolation, the third chapter of Jon Claerbout‘s book Image Estimation by Example is added to the collection of reproducible papers (with code fragments translated from Fortran-90/Ratfor/Loptran to C).

Model fitting by least squares, the second chapter of Jon Claerbout‘s book Image Estimation by Example is added to the collection of reproducible papers (with code fragments translated from Fortran-90/Ratfor/Loptran to C).

Basic operators and adjoints, the first chapter of Jon Claerbout‘s book Image Estimation by Example is added to the collection of reproducible papers (with code fragments translated from Fortran-90/Ratfor/Loptran to C).

Another old paper has been added to the collection of reproducible papers:

• The Wilson-Burg method of spectral factorization with application to helical filtering

Several new wiki pages appear now on the web site:

• Adding new programs to madagascar (Thanks to Nick Vlad)
• Introduction to madagascar
• Guide to RSF file format
• Guide to madagascar programs

The last three are latex2wiki (scons wiki) conversions of the earlier LaTeX documents.
The last one also uses a new feature of sfdoc, which can now output

• command-line selfdoc (by default)
• fancy HTML pages (sfdoc -w)
• LaTeX documents(sfdoc -l)
• MediaWiki-formatted documents (sfdoc -m)

Please feel free to edit, expand, and correct the wiki pages. Have fun.

SEGTeX, a LaTeX package for geophysical publication, has found a new home on SourceForge.
The new central web page is http://segtex.sourceforge.net (redirected).
If If you have been using Subversion to access the package before, please run

svn switch --relocate http://egl.beg.utexas.edu/svn/texmf https://svn.sourceforge.net/svnroot/segtex

once inside the top directory. To obtain an upload permission for “svn commit”, please register with SourceForge and send me your username.
