[CIG-SEISMO] SW4 prefilter in SRF file

[Aaron Moya]

Hello:

In SW4 the prefilter option is used to remove unresolved motions. I
understand it can be used to create movies. In order to use it, the
source term must have the "t0" option set to a large enough value in
order to avoid unphysical oscillations due to an abrupt start.

In case of not using  a single source but a SRF file with the rupture
option, how does the "prefilter" option work? There is no "t0" option.
What happens to the images obtained from the image command? Are they
also filtered?
