sfconjgrad is a new program for a generic conjugate-gradient least-squares inversion. A short description of it has been added to the RSF programs guide.
Update on FFT sizes: sffft1, sffft3, sfcosft, and some other programs that use FFT, now pad the data to the nearest optimal size.
A section on sfreal and sfimag has been added to the RSF programs guide.
Following a suggestion from James Rickett, I have redesigned RSF I/O to keep complete processing histories in RSF files. Please let me know if this causes any troubles or if you get other suggestions.
sfdots cannot handle irregular data at the moment. However, you can plot regular data with holes. See an example in rsf/rsf/sfdots.
sfheadercut is a new program for header-based zeroing of traces in RSF files. It is related to sfheaderwindow in the same way sfcut is related to sfwindow . A short description has been added to the RSF programs guide.
This program is based on Gilles Hennenfent’s applymask.
